MARTIN: We're here in North America, in the northern reaches of the Eastern woodlands.

It's us, the Kratt Brothers!

I'm Chris.

I'm Martin, and today we're doing something really fun.

We're looking for animals named Martin!

(Laughing) There's a creature who lives here at the Ecomuseum.

A creature you've just got to meet.

Meet the pine marten.

MARTIN: What a creature.

For starters, love the name; Pine marten.

And you didn't even name it.

I know!

(Laughing) MARTIN: Oh, she's on the move!

Such a great climber.

Oh, that's the number one pine marten Creature Power.

Climbing ability.

Huh, Chris?

You impressed?

CHRIS: Oh yeah!

MARTIN: They not only are great at climbing in the trees, they climb at full tilt, at full sprint.

They're racing through the trees, chasing after their favorite prey, the red squirrel, who's a great climber also.

Those red squirrels are trying to get away.

The pine marten has to be faster.

CHRIS: Martin, I think she likes you.

(Laughing) (Gasping) Oh, she's sniffing!

Pine martens are always on the scent trail of their prey.

They use their nose for hunting.

MARTIN: She sniffed out your hiking boots pretty easy, Chris.

(Laughing) Hey, I'm not sure which Martin I like better.

This one or my brother?

Hey!

Oh, you're right, the pine marten's way cooler.

CHRIS: Wow!

That is one cool climbing creature!

Named Martin, by the way, with some amazing Creature Powers.

Nobody can run around through the pine trees like a pine marten can.

Yeah, imagine if we had pine marten powers!

BOTH: What if!

Aah!

Ow!

Oh, applesauce.

Yuck.

(Buzzing) What's that?

(Yelling) Whoa, hey!

Easy, buddy!

Oof!

Oh... Oh no.

(Stammering) Oof!

(Sighing) (Groaning) Ooh, that martin is really bugging me!

Why?

What did he do?

Well, when I fell out of the tree into a pile of old apples, the apples smushed into applesauce.

The applesauce got all over my shirt which attracted the flies.

Ooh, that martin keeps dive-bombing me.

I don't get it.

Why would Martin do that?

(Whistling) Looks like he's just relaxing.

(Whistling) And he actually whistles pretty good.

What?

No!

He's bugging me!

Come on, I'll show you!

Watch.

(Whistling) BOTH: Whoa!

Yikes!

That's why!

That martin wants to catch the flies, and he keeps dive-bombing me!

Ooh!

Whoa, and he really cuts it close!

(Laughing) We thought you were talking about your brother!

Yeah, but why are you calling that swallow-like bird Martin?

Because that bird is called a purple martin!

The purple martin is the biggest swallow in North America.

Did someone say purple martins?

My avian namesake!

I love purple martins.

The only thing that could make me love them more is if they were called blue martins!

But I see why they call them purple.

Look at its color.

It's so pretty.

CHRIS: Uh-oh, another dive!

Hit the dirt!

(Yelling) Whoa, what a pull up!

What turning!

Wish I could do that with the turtle ship.

Yeah, right!

It is such a fast flying bird.

It has to be in order to catch insects out of the air.

Peregrine falcons are fast, hummingbirds can hover, but not many birds can pull off the high speed aerial maneuvers of my boy, the purple martin.

(Buzzing) Yeah, when I look at it that way, that martin doesn't bug me anymore, not at all!

Thanks, bro!

This one, sometimes.

Are you thinking what I'm thinking?

That you can stop hugging me now?

No, come on!

Don't you want purple martin powers?

Yeah, of course!

Look how he moves.

I can hardly wait to get up there with him.

ALL: Whoa!

Okay, here it comes.

Oh please, make me a purple martin suit!

Yeah, come on, please!

I've seen the light, the purple light!

Yeah, please, purple please, purple please...

BOTH: Purple please!

Okay, okay!

Aye-yi-yi, you don't have to beg.

Why wouldn't I?

These birds are awesome, and I love the science of flight.

Aerodynamics, wind pressure, lift.

It's like an avian fighter jet.

And these birds have got it going on!

Give me some more observations.

KOKI: Wings are for lift.

JIMMY Z: Tail moves like a rudder.

CHRIS: Quick wings flaps to gain speed.

MARTIN: Tuck wings for rocket speed.

KOKI: Spread wings... JIMMY Z: And tail... CHRIS: To slow down... MARTIN: And land...

BOTH: Right in front of us!

Bros, that's not the purple martin.

It's not?

No, it's not purple, it's black.

But every other feature is screaming purple martin.

The face, the wings, the beak, the tail feathers.

That's it!

The feathers.

I can explain this one... with this.

With a triangle?

Yeah, Jimmy, it's a prism.

Watch, sunlight is made up of different colors.

We can't see them, but when you shine a light through the prism, it's refracted, meaning it splits and you can see the colors, like a rainbow.

Some bird feathers can do the same thing.

When little or no light is reflected, it looks black.

But if you move or more light hits the feathers, it's refracted and produces color!

ALL: Whoa!

JIMMY Z: That's pretty purplish.

Hmm, I'm seeing a lot of blue in that purple.

Well, if it's called a purple martin, the suit has to be purple.

Sorry, no blue or green today.

BOTH: Huh?

Is she serious?

Or just kidding?

(Chuckling) Listo!

Aw, who cares?

Let's just...

BOTH: Activate purple martin powers!

♪ Woo-hoo!

Whoa, check out these wings!

Yeah, this is one slick suit.

And... jet black.

Where's the color?

You're standing in the shade.

Get in the sun.

Yeah, let's refract some light on this martin power suit.

Oh yeah!

I'm green!

A green martin.

Wait a minute, I'm green.

And so I'm still Chris...

I think.

I'm blue!

I don't believe it!

This is even better than a purple martin.

I'm a blue martin!

Uh, I'm a green martin?

Okay, wait a second, I like the green part, but I'm not so sure about the martin part.

(Laughing) Funny, bro!

Any color martin's are awesome.

Okay, being a martin, this is going to be one confusing creature adventure.

(Chirping) Purple martins on the move!

Wait up, bro!

Follow those martins!

To the hoverbikes!

C'mon, Chris.

Oh, I mean, green martin.

Oh boy, this is going to be a tough creature adventure.

MARTIN: Come on, green martin!

CHRIS: Let's stay on his tail.

At least these powers are awesome!

Wow!

Amazing!

Look at all the purple martins!

I think maybe they're catching bugs over the river.

Where are the bros!

Let's see.

Purple... Blue... Green!

Follow that pattern: purple, blue, green.

ALL: Purple, blue, green!

This is the perfect hunting grounds for the purple martin.

Insects are hatching out of the river.

And today it's... Mayflies!

Whoa!

Out of the air!

CHRIS: Off the surface!

MARTIN: He takes a sip of water to wash it down.

Wow!

Oof!

These powers are so awesome, you can't help catching insects.

Cool!

MARTIN: There, I heard you!

You admitted it.

Martin powers are cool.

Yeah, well, the bird martin powers, I mean.

Hey, check it out.

(Chirping) Why are they all going over to the riverbank?

Let's find out.

It's a purple martin colony.

This is rare.

What do you mean rare?

There's so many of them!

Well, yeah, they're colonial nesters.

But it's very rare to find them nesting in natural cavities anymore.

KOKI: Check it out.

Today, purple martins on the East Coast only nest in gourds and houses put out for them by people.

Martin's right.

He should be; they're talking about Martins.

(Chirping) Wow, purple martins are so nice.

Like Martins usually are.

Oh boy, here we go.

Look how they all get along.

Nesting so close to each other.

CHRIS: Oh, look.

One's feeding a mayfly to a chick!

(Laughing) He eats just like me.

Hey, little buddy.

Oh, naming you is gonna be easy.

I'll call you... Oh no, don't do it, brother!

Why not?

It's perfect.

(Chirping) Please, no!

Martin Junior!

(Groaning) How much more of this can I take?

I think that's a really good name.

Hmm, I would've preferred Martinito!

Hang in there, Chris.

(Chirping) Hey, Martin Junior, where are you going?

There's something happening outside.

Guys, can you find out what's alarming the colony?

AVIVA: There!

JIMMY Z: On the cliff.

Some kind of weasel!

Yes, something other than an animal named Martin!

You're right, that's definitely a member of the weasel family.

Some kind of mustelid for sure.

But what kind?

Going in for a closer look to get an ID.

Oh no... no...

Please no... anything but that!

I don't believe it!

No!

(Moaning) What's wrong, Chris?

It's a pine marten!

Did you say Martin?

Oh brother.

What?

Another animal called Martin?

This is my lucky day!

Hanging out with the other Martins of the creature world!

Something tells me this is NOT going to be my day.

Come on, Chris!

And now we have a new creature mission!

Let's go!

Well, I can't resist a creature mission!

Our mission: follow that marten and get pine marten powers!

Hey, any creature adventure is a good creature adventure.

So why not?

Sights set on pine marten.

I'm going in.

MARTIN: That a boy, Chris!

Whoa, that was close!

Hmm, where'd he go?

Doing another pass!

Hmm.

Where could he be?

(Squeaking) Huh?

Whoa!

(Yelling) Ow!

(Groaning) Huh?

Hey, you accidentally put on my Creature Power Vest!

(Gasping) Wait!

Hey squirrel, wait!

(Squeaking) What?

You ran into me!

(Rustling) Uh-oh.

Oof!

(Yelling) Oops, missed the branch!

(Yelling) Well, I'm glad this is a climbing adventure.

Hey!

Hey, hey squirrel!

Come back with my Creature Power vest!

(Yelling) Gotcha, bro!

Martin, forget about me!

You've got to catch that squirrel and get my Creature Power vest back.

I won't be able to activate any Creature Powers without it.

(Moaning) I'll be Creature Powerless forever!

It'll be okay, bro.

I'm going after that squirrel.

Hey guys, take care of Chris!

(Yelling) (Moaning) A squirrel stole my Creature Power vest.

(Sobbing) Wow, this is not Chris's day.

We should take him back to the Miniaturizer.

And get him real size.

This is a rough day for my brother.

I've got to get his vest back.

So where is that vest-snatching squirrel?

Hmm, there's a pine marten, but no squirrel.

She could be anywhere within this coniferous forest.

The best way to find the squirrel wearing Chris's power vest... ...is to use pine marten powers.

Right, Aviva?

You're right.

To help Chris, I'll make you a pine marten power disk.

Wahoo!

(Laughing) First purple martin powers, and now pine marten powers.

Oh, is this my birthday!

Well, enjoy it, Martino!

And while you're at it, make some observations of the pine marten.

And get Chris's Creature Power vest back.

Oh, this is the worst day ever.

(Moaning) And pronto!

That's a 10-4.

Locking in on pine marten.

Hey, Marten.

(Laughing) Can it get any better than this?

CHRIS: Oh boy... Aw, cheer up, Chris!

Yeah, when something's not going your way, it's best to try and do something to make it better.

Yeah, like get back out there and get your vest back.

Okay, brr, okay.

Shake it off.

Yeah!

I'm gonna save my Creature Power vest!

I'll come too, and I'll bring my mobile invention kit.

I can program as we go.

All right, I'll drive!

AVIVA: Yeah, that's better.

I shouldn't really program and drive.

Let's motor.

We've got to get my Creature Vest back from that slippery squirrel.

Aw, it doesn't get any cuter than that.

Aww!

CHRIS: Hey, Martin!

Hey guys, look!

I just found a little pine marten, and I'm just thinking about what to call him.

And I'm gonna name you... Lil' Marty.

(Groaning) That's cute, Martin.

But give me some observations I can use for the programming.

On it!

Hmm, claws for climbing.

Check!

Hmm, what else?

(Chuckling) Looks like it's playtime with mom!

A long lean body that makes him look like a furry four-legged snake sliding lightning fast through the trees.

Check!

Whoa, nice leap!

Their balance is incredible, when running on branches and leaping from tree to tree.

That balance is the main thing.

It's the thing that makes it possible for the pine marten to chase his favorite prey who are also great at running through the trees: squirrels!

Cornering them in the trees.

That's how pine martens catch red squirrels.

Pine marten power disc is complete!

Oh, perfect timing!

Activate pine marten powers!

♪ Wow, pine marten powers are awesome!

I feel like running through the trees.

Aww, I wanna do that!

(Sniffing) And another power I didn't expect.

My nose is finely tuned.

(Sniffing) I smell squirrels.

Well, follow that nose right to the squirrel who stole my Creature Power vest.

I need it back!

You got it, bro!

(Sniffing) Red squirrel that way!

(Grunting) Oh, this is not a good day for me.

I lose my Creature Power vest on a day we're adventuring with those climbing powers!

Hang in there, Chris.

The day isn't over yet.

MARTIN: Heh, strange, he kind of reminds me of Chris.

Oh, and that's a good thing, because I have a lot of experience tackling my brother.

Hey, Chris!

Your vest is heading your way!

All right!

Come on vest, right over here!

Oh ho, yes.

Gotcha!

Huh?

MARTIN: I'll get him!

Ah, don't go in there!

(Laughing) (Yelling) Steady!

(Laughing) Huh?

Aah!

No!

(Laughing) Don't go in there!

Stop!

(Laughing) Please stop!

Wait, my vest!

Uh-oh.

(Yelling) Aww, I'm the climbing brother.

Not the swimming brother.

This is definitely not my day.

(Laughing) Come on, Chris.

Hang in there.

Day's not over yet!

Okay, now I've got you in an isolated tree.

I think this is the end of the chase.

No squirrel can leap that far.

Now that's pine marten powers!

Hey, Chris, brother o' mine.

Look what I found!

Yes, my vest!

You're back!

My Creature Power Vest!

I'm never taking you off again.

All right, still a little daylight left.

Come on, let's get back out there and adventure with the other Martins.

Thanks, but I've had enough for one day.

I'm just going to hold onto my vest, go into the Tortuga, lie down, and think of some animals that have Chris in their name.

Hmmm, hippopotochris?

Nope.

Rhinocochris?

Nope.

(Laughing) We'll help Chris think of Chris animals tomorrow.

Because isn't today a day for the Martins or what?

(Laughing) (Laughing) Martining free and in the wild!

CHRIS: So, summer is here, and there are a lot of great things about summer.

One of the best is it's purple martin nesting season.

And we've got a whole colony of nesting purple martins right here!

CHRIS: Awesome!

Males and females.

MARTIN: Yeah, the males are the black ones that when the sun hits them just right, they shine a bluish purple.

That's why they're called a purple martin.

Well, that's why they're called purple, but I'm still not sure why they're called martin.

But I like it!

They like to sit and rest on their balconies.

(Laughing) MARTIN: They do.

Look, there's a pair right next to each other, the male and the female.

They've got a nest of eggs, or maybe chicks already.

CHRIS: Each pair of purple martins has it's own hole, it's own nesting chamber in the house.

And they're working together to raise chicks.

It's a short summer season, so they're really, really busy.

They've got to feed up their hatchlings so that they're ready to fly.

So they're strong and healthy.

So they can make their migration south to the rainforest, to the Amazon rainforest which is where they spend the winter.

Purple martins are cavity nesters.

They nest in holes.

Sometimes natural holes, but more and more they like to live in the nest boxes that humans set up for them.

And they have to be nesting together in groups.

The more purple martins there are, the more successful their nesting season is going to be.

Whoa, here they come!

Purple martins flying all around!

(Laughing) That is an amazing flying power!

CHRIS: Purple martins are masterful flyers.

They're built for high speed turns and dives.

That's because they chase insects on the wing.

They pick them off in mid-flight, so they have to turn quick to catch their prey.

So purple martins are a bird with some amazing Creature Powers.

Well of course, they are named Martin.

(Laughing) Hey, keep your eyes peeled for this amazing purple martin this summer and keep on creature adventuring!

We'll see you on the creature trail!
