My Name is agent Olive.

This is my partner, Agent Otto.

This is between a rock and a hard place.

But back to Otto and me.

We work for an organization run by kids that investigates anything strange, weird, and, especially, odd.

Our job is to put things right again.

(theme music) (Otto screaming) (roaring) - Squishinating!

- (Olive): Who do we work for?

We work for Odd Squad.

- Thanks for coming, Odd Squad.

- No problem.

- Do you realize you're all wet?

- That's because every time I try to take a drink of water, this happens.

Aren't you gonna say, "Whoa"?

- No offense, but we've kind of seen this before.

- (Olive): We got this.

(Ding!)

Try it now.

(sigh of relief) - Thanks, Odd Squad.

- Have a good day.

- Ah... Mmm.

Hmm!

Ah!

I thought, because I was eating salad... that salad was gonna fall.

Haha!

Thank goodness.

OHHH!

For the love of...!

Odd Squad!

I try to be healthy.

(screeching like a monkey) (smooth jazz music) - Whoa!

Where is everybody?

- Must be a holiday.

- Uh, nope.

Holiday hats are still here.

- (Ms. O): Olive, Otto, in my office!

There you two are, something very odd has happened.

I'm invisible.

- WHOA!

- And it's all the work of... (dramatic musical cue) What was I saying?

- Oh, you were saying who did this.

- (Ms. O): Right.

Odd Todd did this with invisible ink.

- Oh!

Let's just use the revisible-inator gadget and make you visible again.

- (Ms. O): That's when things get tricky.

- Oh!

Hello, Agents.

I bet you are looking for the revisible-inator.

But since you don't have it, I'm going to turn everyone invisible, including every Odd Squad agent!

(laughing maniacally) - We need to warn the agents.

- (Ms. O): A bit late for that.

- (Orchid): Already invisible.

- (Oscar): Hey, guys, invisible Oscar!

- (Obfusco): Obfusco's here too!

- (Dr. O): What's next?

- Wait!

Who else is in here?

- (Ms. O): Every agent we've got.

I think you're standing next to Olaf.

- (Olaf): POTATO!

- (Otto and Olive): AAH!

- (Ms. O): Yep, it's Olaf.

- We're in trouble.

- (Ms. O): Not necessarily.

Over here, people!

It seems Odd Todd wants to play a game.

- I'm hiding this gadget at a secret location in town.

To find it, you'll have to figure out all my clues.

(Odd Todd slurping) Mmm!

Yummy hot chocolate!

- Well, that doesn't help us at all.

- Yes, it does, Otto.

He's going to Polly's Hot Chocolate Stand.

- (Ms. O): Well, what are you waiting for?

GO!

(agents crying out) - Sorry, sorry.

(weird unknown sound) Strange, Polly's not here.

- (Polly): Yes, I am.

- (both): AAH!

- (Polly): I'm invisible.

- Did Odd Todd happen to leave a clue?

- (Polly): Matter of fact, he did.

- Hurray!

You found the next clue!

Hoo!

Hoo!

Hoo!

Isn't this exciting?

- (both): NO!

- I can't hear what you're saying because this was recorded earlier.

- Just give us the next clue.

- Hopefully, you've asked me for the next clue by now, so here it is.

The gadget is located in a building on Main Street, and the address doesn't end with the numbers 1, 3 or 8.

- How is that helpful?

- Be skiing ya!

Ha!

Hee!

Hee!

- There are one hundred houses on Main Street.

I'll pull up a hundreds chart to help us.

- (Polly): What's that?

- (Olive and Otto): AAH!

- (Polly): Oh yeah.

I'm looking over your shoulder now.

- A hundreds chart is an easy way to keep track of what the number could be or couldn't be.

- Odd Todd said the address couldn't end with 1, 3 or 8.

- (Polly): Why did so many numbers go away?

- On the hundreds chart, when you take away all the numbers that end in a certain digit, the entire column gets crossed out.

- But there's still so many addresses left.

- Odd Todd skied away at the end of his message.

I think that's a clue where to go next!

- Ski rhymes with knee.

And when you clean, you're kneeling.

The water tower is always super dirty.

I bet he's headed over there to clean it.

- Or maybe Todd's headed to the Bears' ski-team practice?

- Sounds farfetched but sure.

- Polly, we're gonna get that gadget, you have my word.

- (Polly): I'm doing the high-five thing.

- I'll just see you later.

(electronic beeping) Here!

The ski team's not here!

(whistle) - (man): We are here, all right!

- (both): AAH!

- Coach Roberts?!

- (Roberts): Odd Todd covered my whole team in invisible ink.

We can't race if we're invisible.

At least, not in this league.

- Did he leave any clues?

- (Roberts): In fact, he did!

I'm pointing to the ground right now, but I'm invisible, so... - Scribbles!

I turned your favorite team invisible!

How odd!

(Odd Todd laughing maniacally) Tell you what, I'll make it up to you with another clue.

The address the gadget is located at is greater than 25, but less than 60.

But hurry up, time is running out.

(laughing maniacally) But seriously though, you should hurry.

- OK, so "greater than" means bigger, and "less than" means smaller.

Bigger than 25 means we can eliminate numbers 1 through 24.

- Odd Todd said it has to be greater than 25, which means it can't be 25 either.

Has to be at least 26.

- (Roberts): Hey, you guys ever notice you do a lot of math?

- And he said the address on Main Street is less than 60, so that means we can eliminate anything greater than 60.

Still so many addresses left.

Did he leave another clue?

- (Roberts): You betcha!

- Are you pointing at something again?

- (Roberts): Ah, I'm so bad at this being invisible thing.

It's on the ground to your left.

- A baby bottle?

With milk inside?

Milk and Moon both start with the letter M. The Moon controls the waves.

Who likes going to the beach?

Baby Genius!

- Kind of a long way to get there, but I think you're right.

- What does this string do?

- OTTO, NO!

Invisible ink!

- (Otto): Oh no!

I think I'm invisible!

Let me get my mirror to see.

Oh no, my mirror is invisible too!

- Otto, it's gonna be OK. (theme music ringtone) Go for Olive.

- (Ms. O): Olive, I need an update.

- Otto's just turned invisible.

- (Ms. O): That is not what I wanted to hear.

- Ms. O, I'm gonna find that gadget.

I promise you.

- (Ms. O): Send Otto back to headquarters.

- Otto, bring Coach Roberts and the team back to HQ.

- (Otto): You got it.

- I'm gonna go find out the next clue with Baby Genius.

- (Otto): Good luck, partner.

OK, team, follow me!

- (Roberts): OK, where are you?

- (Otto): Ugh!

Being invisible is hard.

(melancholy music) (sound of eagle screaming) (Olive sighing) (bang) - AH!

(baby laughing) So that means Baby Genius should be right over...

HERE!

Huh?

Nothing.

- Hello!

- AH!

Rivka?

- (Rivka): I'm here.

The odd boy made me invisible.

He left a clue.

- "The address has 2 digits that, when you add them together, equal 8.

- (Rivka): I believe he means the first number plus the second number has to equal 8.

- OK, well, I know that 4 plus 4 equals 8, so maybe... 44.

- (Rivka): Well, I know that 2 plus 6 is 8, so maybe 26.

- 3 plus 5 equals 8, so it could be 35.

None of the other numbers will work, so the address is either 26, 35 or 44 Main Street.

(theme music ringtone) Ms. O, I'm getting closer.

- Very close.

- Todd!

- [Hurry, Scribbles,] you have less than 5 minutes before I destroy the gadget, and you'll [never see your friends again!]

Get it?

'Cause they'd be invisible and you can't see something when it's invisible.

So you would see-- - I get it!

Now give me the next clue.

- You have all the information you need.

[Odd Todd out.]

(dial tone) - How can I figure this out?

26, 44 and 35!

What would Odd Todd do?

- (Rivka): Something odd.

- He would so something odd, so he'd pick the odd number!

26 ends in a 6, which is even.

And 44 ends in a 4, which is also even.

But 35 ends in a 5, and you can't split 5 into 2 equal parts, which means it's an odd number!

Todd is at 35, Main Street.

- (Rivka): You go girl.

- Hmm!

Scribbles!

You did it!

- Why are you in a white box?

- I just like it so much better than the green box.

So tacky!

- Hand over the gadget, Todd!

- Ha!

Ha!

Ha!

Ha!

You didn't really think I'd give it to you now, did ya?

(electronic sounds) - But you said as soon I found, you, you-- - I'm a villain!

I lie!

And now you are gonna get to see me destroy this gadget, all alone.

(laughing maniacally) - Wrong!

- What?

- I'm not alone.

I brought all of Odd Squad with me.

(overlapping chatter) - (boy): That's right!

- (girl): What's next?

- (Ms. O): Not so fast.

- Give it up, you're surrounded.

- Very well done!

But what do you want to catch, hmm?

Me or the gadget?

- One of you is gonna catch it, right?

- Obfusco is not near that.

- (girl): We're not anywhere near that.

- Crumpets!

♪♪♪ - Grr!

Bye for now, Scribbles!

And to all you other invisible agents too!

I can't really see your faces, so sorry I wasn't more specific.

(Odd Todd laughing maniacally) - Well done, everybody!

What do you say we all head back to headquarters?

- (boy): Good job!

- Whoa!

Whoa!

Slow!

OK, this is kind of weird, but cool.

High fives!

High fives!

- Greetings, Agents.

Here in the North Control room, a group of highly skilled technicians look for odd activity around town, like these trees with no trunks, and this trunk with no elephant.

With so much odd activity, it really helps to keep track of the cases that are solved and unsolved.

Right now, there are 8 unsolved cases and 6 solved cases.

So that means the unsolved cases are greater than the solved cases.

I like to think of the greater-than, less-than symbol as a hungry alligator that always opens its mouth to the greater number.

Chomp!

Chomp!

Chomp Chomp!

Chomp!

Chomp!

Chomp...

I was just showing them the, uh... thing.

Ha.

Man!

Time flies when you're solving cases.

Take a look at this.

This symbol turned around.

That's because 1 unsolved case is less than 458 solved cases.

And it still opens up its mouth to the greater number, like an alligator.

Ha!

Ha!

Hey, uh, what's that last unsolved case?

(indistinct whispering) This?!

Oh, this is just a puppet.

I can take it off anytime I want.

What?

How deep does this thing go?

- There you are.

Something very odd has happened.

Yes, I'm talking to you with the glasses or no glasses.

Take a look at this.

These cute, fuzzy creatures are called Centigurps, and Odd Squad headquarters is full of them.

Help up capture all the Centigurps so we can get back to solving cases.

Go to pbskids.org and become an Odd Squad agent today.

Odd Squad needs you!

- What seems to be the problem, ma'am?

- I'm trying to do some quiet reading here, but every time I turn this lamp on... (loud alarm ringing) IT'S WAY TOO LOUD FOR READING!

- Not to worry, ma'am, I have a bright idea.

(Ding!)

See what I did there?

- Otto... - Right.

- Try it now.

- No noise.

Thank you, Odd Squad.

- (Olive): Happy to help.

Enjoy your book.

- (feminine voice): IT WAS THE BEST OF TIMES.

IT WAS THE WORST OF TIMES.

IT WAS THE AGE OF WISDOM-- - ODD SQUAD!

- What seems to be the problem, Ms. O?

- There you two are.

Something very odd has happened.

- Let me guess.

To the zoo?

- (Olive): The zoo?

- I left a pair of gloves there.

I was just hoping if you sent us, I could have gone-- - You are both staying inside headquarters to investigate a crime.

Dum!

Dum!

Dum!

(dramatic musical cue) - Inside of headquarters?

What happened?

- Agent Obfusco was relaxing in the break room... - And now, like a pig at a waterpark, I shall enjoy this sandwich.

(breaking sounds) (cat meowing) What happened to the lights?

My moustache!

It's gone!

- Someone stole Obfusco's moustache?!

- Yep.

He's taking it pretty bad.

- (man's voice): Obfusco!

- Without my moustache, I can't solve odd cases anymore.

- Listen to how clearly he's talking.

- Yes, it is a weird side-effect.

- Weird?!

The way you used to talk was weird.

- (Olive): Maybe, this is for the best.

- NO, IT'S NOT!

He thinks he can't solve cases, which means I'm down an agent, which means you two have to find it.

- Uh, why us?

- You were the only agents not in headquarters when it was stolen.

Wait!

It gets worse.

- We didn't say anything.

- Good, because it gets worse.

You'll be working with Agent Obfusco to help solve this case.

- How are you guys not cold underneath your noses?

Brrr!

- What are you waiting for?!

GO!

- (Olive): All these agents were in headquarters at the time, so it could have been any one of them.

- Or even this pastrami sandwich.

- Otto?

- Hey, it was in the break room.

I just want to make sure we cover all the angles.

- What we really need to do right now is narrow down this list of suspects by questioning them all.

- Great idea!

I'll go ask them what they had for breakfast.

- Yes!

- No!

No, no, no.

The question we have to ask has to be about reasons people might steal it, like... who got into the most arguments with Obfusco.

- (Otto): How will that help us?

- Maybe, somebody was so confused by the way Obfusco talks, they got into an argument and he stole his moustache out of frustration.

- Ahh, I got you, I got you.

Obfusco, can you tell us which agent you argued the most this week?

- Yes.

Right after I finish moaning.

(Obfusco moaning) OK, here we go.

Let's see...

I argued with Ms. O the most-- - Oh!

Oh!

Let's just stick with agents.

- Sure.

You might want to get a marker and a chair and maybe some water.

This will take a while.

- On the vertical column, we have all the agents, not counting Ms. O, who were here when Obfusco's moustache was stolen.

And this horizontal row will have all our different questions.

But we'll start with the number of arguments each agent had with Obfusco.

- Those lines look like little moustaches.

- Uh, they're tally marks.

Each one stands for one argument.

We use those to keep track of all of them without having to start from zero all every time.

- Take Dr. O as an example.

She had 1, 2, 3, 4 arguments with you this week.

- Same with Oren and Ori.

- And Olaf.

They're all equal, which means that none of them are more likely or less likely to be the one that stole your moustache.

- But if you look here, all the way at the bottom, agent Orchid has way more than 4 tally marks, so she's likely the most frustrated with Obfusco and stole his moustache.

- I'll go track down Orchid.

Orchid and I have history.

- Wait.

What am I supposed to do here?

- Keep Obfusco away from that marker.

- OK. No, no, no!

Give me that marker!

Ugh!

You have another one of these?

- No.

- Hey!

OK, give me the marker!

Give me the marker!

- No!

No, please.

I need it!

- No, you don't need the marker!

- ♪ La la la la la ♪ - Orchid, stop right there!

- Yeah?

No thanks.

- I know you're the one that stole Obfusco's moustache.

- Excuse me?

- You had the most arguments with him this week, so that makes you our number 1 suspect.

- No, because you don't even know what we were arguing about.

- I insist!

You go first!

- No, you go first!

- You're the best agent!

- No, you're the best agent!

- You're the best at arguing!

- No, you're the best at arguing!

We show how much we like one another by arguing.

I'd never take his moustache.

- OK, I'm sorry for saying you did.

- And to show me how bad you feel, you'll do all this work for me!

(laughing diabolically) ♪ La lala lala lala ♪ - So, if Orchid didn't take Obfusco's moustache, we can cross her off our list of suspects.

- But still, there's a ton of suspects left.

Still gonna take forever.

- You want to talk forever?

I've been growing my moustache since I was 2 years old, and now it's gone!

- Otto, we're gonna need to bring these people in here, one by one.

- It's time to play a little, uh... good cop, bald cop.

(electric razor buzzing) - Otto, no!

It's good cop, bad cop.

- Let him do it.

I can use his hair to make myself a new moustache.

- OK, that's gross.

- I'm... Yeah.

- Where were you this morning?

- Where were you when Obfusco's moustache was stolen?

- Don't be putting the blame on me.

I haven't done anything.

- What did you eat for lunch?!

- Are you really a doctor?

- I didn't do anything!

- Did you eat the sandwich?

- (Olive): Who are you again?

Think, Ori!

How many cases did you solve last week?

- I can't remember!

- Maybe this will jog your memory.

- A puppy!

(puppy yelping and barking) - You're welcome, buddy.

- Otto, you don't buy people puppies!

- See?

This is where you're the bad cop.

- This is gonna take forever.

Ahhh...

Wait.

Where's Obfusco?

- (man's voice): Obfusco!

- Here.

I tried to buy a moustache on the black market.

There were none left.

- OK.

According to my notes, Oren solved the least amount of cases: 5.

- It looks like he has 4.

But you crossed them out, so it should be zero cases, right?

- I didn't cross it out.

This is how you count 5 when you're using tally marks.

- It helps you add things faster because you're counting by fives.

Like Dr. O: 5, 10, 15, plus 1 more equals 16.

- Yes, but how does this help me get my lucky moustache back?

- Well, Oren solved the least amount of cases last week: 5.

Maybe he thought he would solve more with your lucky moustache!

- Uh, just so we're clear, it's not lucky.

- Then, why did I just drop this mug?

Bad luck!

- I'll go talk to Oren.

- The reason I didn't solve many cases last week is because Ms. O asked me to help her with a case she's been trying to solve for weeks.

- Great!

Another dead-end.

- You know it's funny, but from here, that didn't sound like an apology.

- I'm sorry for saying you stole Obfusco's moustache.

- Great.

Now, say it into this tape recorder.

(Beep!)

- I'm sorry for saying you stole Obfusco's moustache.

(Beep!)

- Fantastic.

And to show me how bad you feel, you're going to do Orchid's laundry for me.

- Why are you doing Orchid's laundry?

- Well, it all started with-- - Oren!

- I've said too much.

(Orchid laughs diabolically.)

♪ La lala lala lala ♪ - This is horrible!

- I know!

I can't tell which cup is mine!

- And the case.

The case is horrible.

- Yeah, that too.

I mean, we haven't got anything yet!

- What about the special key?

- What special key?

- You know, the one that can turn off the lights in headquarters.

Whoever has it... - (Olive and Otto): Stole your moustache!

- Yeah, that.

- Did you have the special key?

- I'm a doctor, not Ms. O!

- For sure, Ms. O has it.

- Ms. O has it!

- I wanna say potato, but Ms. O.

(whispering): Potato.

- It was Ms. O.

- Are you sure?

It can't be Ms. O. Ms. O wouldn't do anything like-- - Remember when you asked me about my confusing conversations?

Let's see.

I argued with Ms. O the most.

And when we were trying to figure out who was having a hard time solving cases... - The reason I didn't solve many cases is because Ms. O asked me to help her solve a case she's been trying to solve for weeks.

- And who has the special key that can turn off the lights?

- (both): Ms. O!

(clapping) - You're right.

It was me all along.

- But why would you... Can you stop clapping?

- I wanted you to see you don't need your moustache to solve cases.

You're a good agent on your own.

- She's right.

You came up with all the right questions to ask the agents.

- And you realized the key to the case was... well, the special key.

- Sweet cricket sticks!

You're right, like a streetlamp at midnight.

I am the best agent at Odd Squad.

- Oh no, he's confusing again!

- Thanks for your help, Agents.

And if you want your moustache, I'll give it back.

- (man's voice): Obfusco!

- Thank you kindly, but I won't be needing it anymore.

Now, let's go do the cha-cha.

(cha-cha music) (country western music) - Yeehaw!

♪♪♪ (Ding!

Ding!

Ding!)

- Greetings, Agents.

Welcome to the lab where I conduct all sorts of experiments, build gadgets and-- - I'm Olaf.

- That's Olaf.

I asked Ms. O for some help in the lab and she sent me Agent-- - I'm Olaf!

- Which is great because I have a ton of work to do.

The only problem is-- - I'm Olaf.

- He won't stop saying, "I'm Olaf."

In fact, I started keeping track.

These lines are called tally marks.

A tally mark isn't a number; it's just a mark.

In this case, each line represents every time Olaf says, "I'm Olaf."

As you can see, there is 1, 2, 3 of them, because that's how many times he said it.

This is a quicker way of counting, especially when the thing that you're counting keeps on changing... - I'm Olaf!

- ...so quickly.

See?

Now, there's 1, 2, 3, 4 marks, because Olaf said, "I'm Olaf," a total of 4 times.

This is a lot quicker than having to erase and rewrite the number every single time it changes.

Watch.

Any second now, he'll say it again.

Ah!

I guess he's gotten it out of his system, which is great 'cause I have-- - I'm Olaf.

- And there it is.

I'll put another mark down; only this time, I'll do it like this.

Now, I know that this group here equals 5.

- I'm Olaf!

- Make that 6.

So I'll start a new tally mark over here.

5 plus this 1 tally mark over here equals 6.

- I'm Olaf!

- Let's make that 7.

- I'm Olaf!

- Uh, that's 8.

- I'm Olaf.

- 9.

- I'm Olaaaf!

- 10.

And this is just today.

You should see yesterday.

- I am Olaf.

- I'm gonna need another whiteboard.
