♪ Wild Kratts!

♪ CHRIS: We'’’re here off the coast of South America.

MARTIN: In the Caribbean Sea.

BOTH: It'’’s us, the Kratt brothers!

I'’’m Chris.

I'’’m Martin, and swimming in the waters around us is a type of creature who has remained relatively unchanged since the time of the dinosaurs.

It has a perfect design for seafaring and sea living.

Yeah, you know who we'’’re talking about.

BOTH: Sea turtles!

MARTIN: The body design of the sea turtle has been pretty much unchanged for millions of years.

It'’’s the same today as it was way back then.

CHRIS: That shape and design of the sea turtle has enabled it to survive while all the dinosaurs died out.

That'’’s how good it is.

But how is it this good?

MARTIN: Why does it work?

Let'’’s check out this ultimate sea survivor in action.

Hey, how about swimming with the sea turtles?

♪ CHRIS: Huh... not much here.

MARTIN: Ah, the grass flats.

A turtle.

A green sea turtle!

Whoa, look at him go, flying through the water.

A sea turtle can stay underwater for 12 minutes when swimming without coming up for air.

He'’’s not letting us get close.

CHRIS: He'’’s keeping his shell towards us.

MARTIN: I wonder why?

What about all the challenges and dangers of living in the sea?

How did sea turtles survive with all the aquatic mega-dinosaurs after them?

How do they escape the sharks and killer whales after them today?

Imagine if we had the power to swim with the sea turtles.

What if?

Oof.

(Muttering in Spanish) What is up with Aviva?

Hey Aviva, what'’’s going on?

Well, I'’’ll put it this way.

I'’’m troubled... by the Tortuga.

I love the design.

Of course, it'’’s one of my favorite inventions, but there'’’s something missing and I can'’’t put my finger on it.

Ah, what are you talking about?

The Tortuga'’’s great just the way it is.

It has a protective shell like a tortoise, or any kind of turtle.

With plenty of room inside.

And it has retractable legs and head like my favorite land turtle.

Oohhh!

Hey!

Who'’’s that?

He'’’s talking about the box turtle and its incredible ability to retract into its shell completely.

It'’’s a great defense for the box turtle and for us whenever we have to go into lockdown mode against one of our villains.

What in the world are they doing down there?

Whoa!

Can'’’t a person just replace a shell plate without getting jostled?

Whoa!

And who doesn'’’t love camouflage?

The Tortuga has camouflage patterns so it can blend into its background like a box turtle or a leopard tortoise does.

That'’’s why turtle shells have such amazing patterns.

Hmph.

Oh, I like box turtles.

Wait... no, leopard tortoise!

Ah... hm, how about spotted terrapin?

Turtles around the world have shell patterns that can blend into just about any conceivable habitat.

And the Tortuga'’’s got all that too.

And it can even hover like the flying turtle!

(Snoring) Yeah, and flying is really good for... MARTIN: Tortuga hover mode can really spin!

(Screaming) Hmm.

Uh, Martin, cut the hover, cut the hover!

There are no flying turtles.

Oh yeah, true.

I kind of got carried away.

(Koki yelling) (Growling) So you see, Aviva, the Tortuga is great just the way it is.

The Tortuga is absolutely...

Awesome!

Incredible!

Perfect...

BOTH: Just the way it is!

Yeah...but there'’’s still something missing.

KOKI: Uh-huh.

It can'’’t swim.

But it'’’s a good thing I can.

I'’’ll get you, Martin!

Swim... that'’’s it!

That'’’s what'’’s been bothering me.

I never designed the Tortuga so it can move freely in an aquatic environment.

The Tortuga can'’’t swim!

So let'’’s teach it to swim!

Whoa.

Why were you spinning it around like that for?

Yes, modify the design by adding new aquatic features...

Exactly!

Ha ha... sorry, Koki.

I just need some bio inspiration.

Well, we have two basic choices.

Number one: we could check out freshwater turtles like painted turtles, Florida soft shells, or spotted terrapins.

Or number two: sea turtles!

Like green turtles, hawksbill turtles, leatherbacks, loggerheads...

Okay, let'’’s vote!

Everybody for freshwater turtles, hands up.

Okay, everybody for sea turtles, stand on one foot.

Hmm... it'’’s a tie!

Hey, where'’’s Jimmy?

Yeah, Jimmy can be the tiebreaker!

(Snoring) Okay, Jimmy.

We need you to break this tie.

Do you want to go see freshwater turtles or sea turtles?

Sure, I want to see turtles.

He said sea turtles!

But that was "see turtles" like "see with your eyes" turtles.

It doesn'’’t matter.

He said sea turtles!

BOTH: Sea turtles!

Sea turtles!

Sea turtles!

Sea turtles... Sea turtles... Sea turtles... ALL: Sea turtles!

Sea turtles!

Yeah!

Sea turtles!

Sea turtles!

Sea turtles!

Did somebody say sea turtles?

Wait for me!

All right, so while everybody preps to modify the Tortuga for swimming capabilities, let'’’s find the sea turtle that can show us exactly what to do.

Yeah, and the first sea turtle we find, no matter what kind it is, that'’’s the one we follow.

It'’’s a plan!

Wow.

A coral reef.

There must be a sea turtle around here somewhere.

And a lot of other creatures.

Don'’’t get distracted, bro.

But there'’’s something I want to check out over here.

I say don'’’t get distracted, and then what does he do?

Huh!

BOTH: A sea turtle!

But what kind?

Can'’’t tell.

We'’’ve got to get closer.

Whoa, there he goes.

He'’’s fast.

And nervous.

I wonder why?

Well, we'’’ve got to figure out a way to get close to that sea turtle.

Hmm... Hey, I know.

Sea turtles eat jellyfish, right?

So we could hang around pretending to be jellyfish.

Well, two problems with that, bro.

Not all species of sea turtles like jellyfish.

And two, you don'’’t look anything like a jellyfish.

Yeah, I guess you'’’re right.

We don'’’t have jellyfish powers yet.

But what about this?

Why don'’’t we miniaturize down and hide in the reef, so a sea turtle won'’’t see us and then she'’’ll swim right on by.

Nice.

Wait a sec, we can'’’t leave the Miniaturizer there activated.

Any animal could mess with it.

Yeah, we'’’ve done that way too many times before.

That'’’s better.

Okay, Kratt brothers, so what have you got on the sea turtles?

CHRIS: Uh...that they can be kind of hard to find?

Where are you guys?

CHRIS: We'’’re right here.

MARTIN: Just miniaturized and hiding.

But it'’’s not really working.

Yeah, we still haven'’’t found that sea turtle.

Well, we kind of need a sea turtle to show us how to retrofit the Tortuga with swim mode.

Hey, let'’’s head up there and get a better view.

Hmm... Ho ho!

BOTH: A grouper!

Swim for it, bro!

I already am!

Wah!

Wah!

Martin, in here!

Aahh!

Whew, that was close.

What is this place?

Huh?

Not "What is this place?"

What is this thing?

It'’’s alive!

Ooh.

It'’’s eating little creatures that float into it.

We'’’re inside of some kind of animal.

We'’’re inside a sponge.

A sponge?

What does a sponge have to do with animals?

A sponge is an animal!

Will it eat you?

I don'’’t know.

But we can'’’t stick around to find out.

Aah!

Oh, yes we can.

What is going on out there?

Is it the grouper?

Maybe he'’’s attacking the sponge!

Well, I'’’m not going out there to find out.

You go!

Me?

No way, dude.

You do it!

Okay, well here'’’s one way to find out.

Deploy Fishcam!

Great idea, bro.

Okay, I'’’m receiving a picture feed from the Fishcam.

Ah, but it'’’s fuzzy...

Wait, wait... it'’’s something big...

It'’’s unclear.

Was that a mouth?

What kind of animal eats sponges?

We'’’re about to find out!

Uh, I'’’m getting a pretty clear picture right here, bro.

It'’’s a hawksbill turtle.

And of course, the hawksbill sea turtle'’’s favorite food are sponges.

CHRIS: And check it out.

That'’’s why they call this turtle a hawksbill, because the turtle'’’s beak looks just like a hawk'’’s bill and it'’’s designed for cutting into sponges.

AVIVA: All very interesting bros, but not really the kind of observations that will help me retrofit the Tortuga to be able to swim.

Oh yeah.

We can'’’t lose this turtle.

Let'’’s hitch a ride!

Wahoo!

Yeah!

MARTIN: Ho-ho, this is awesome!

And that'’’s what I'’’m going to name you...

Awesome.

Uh... no, wait a second.

Awesome'’’s not a great name.

I'’’ve got to think of something unique, something that fits you better... Now that'’’s more like it.

All right, Kratt brothers.

What'’’ve you got?

CHRIS: Well for starters, the shell of the hawksbill is flatter and incredibly streamlined, so the water flows past it easily as it swims.

Aah!

Whoa!

Okay, so for water mode, we go from a dome shaped shell to a flatter shell so water can easily flow over it.

And with a shell like this, a sea turtle can go on a marathon swim of hundreds and hundreds of miles.

Or sprints of up to 15 miles per hour!

CHRIS: Ho-ho, hang on, Martin!

MARTIN: I am!

Whoa!

Gah!

Hey Aviva, we got something here!

Oh yeah.

What?

The front flippers power the turtle'’’s swim by pumping up and down.

And the rear flippers provide the steering.

Okay, so we need long flippers in the front, with hydraulic pistons for flapping power, and back here, shorter flippers with rotational capabilities for steering.

Check!

We'’’re heading up!

Hi, Aviva.

Hi guys.

The turtle can stay underwater for a long time.

About 10 minutes for a high action dive, and up to 40 minutes for a low action dive.

But always has to come up for air.

Okay, so it looks like the hawksbill turtle breathes from nostrils at the top of its snout, so... why don'’’t we put the Tortuga'’’s new air intake valves right here!

And I'’’ll install bigger air tanks inside for oxygen storage.

AVIVA: Hey, Jimmy!

Huh?

Could you take the master key out of the ignition interface?

We don'’’t want to have the Tortuga accidentally starting when we'’’re in the middle of a modal retrofit.

Got them.

And hang onto them.

They'’’re our only set.

I got them.

What'’’re you guys up to anyway?

MARTIN: Well, it looks like we'’’re getting a turtle-back tour of the reef.

Hey, there'’’s Blimpy the blowfish.

MARTIN: Oh yeah!

And our old buddy Ocean Pony the seahorse.

And hey, there'’’s-- MARTIN: Uh, I don'’’t remember him.

CHRIS: Yeah, that'’’s because he'’’s somebody new.

BOTH: A tiger shark!

Whoa!

♪ Hold on tight, Chris!

I'’’m holding!

I'’’m holding!

Wah!

Chris!

Whoa... gah!

The tiger shark is gaining!

BOTH: Whoa!

Oof!

Whoa, our sea turtle is using his shell like a shield.

And that'’’s what I'’’m going to name you... Shield.

KRATTS: Oof!

But how long can Shield keep this up?

Look at these teeth!

Based on size, tiger shark jaws are even stronger than the great white shark'’’s jaws!

If that shark gets the shell in his mouth or a flipper in his mouth, Shield is done for!

MARTIN: Shield has another plan!

CHRIS: I hope so!

♪ Whew!

That was close.

And another great defense for the hawksbill sea turtle: hiding in the reef.

Yeah, and that'’’s why hawksbills are reef turtles, so they can use the coral reef structure to feed them... and hide them.

Yeah, the shield defense is great when a hawksbill is caught out in the open, but the sure fire plan is to hide out in the protection of the reef.

Hey Aviva, did you catch that turtle power action?

ALL: Huh?

Oh yeah, they saw it.

So Aviva, you up for a little turtle power suit programming?

Uh, yeah.

That was incredible!

Nice shield work.

I never knew sea turtles were so maneuverable.

We saw it all, thanks to the amazing Fishcam.

What?

Hey!

I guess I made the Fishcam a little too fish-like.

Maybe a little.

But hey guys, good news!

We'’’ve finished modifying the Tortuga for underwater travel, so get up here and we'’’ll take it for a test drive.

Cool.

Great!

We'’’ll be right there.

MARTIN: Uh, as soon as Shield tells us the coast is clear.

Great.

All clear.

Let'’’s get back to the Miniaturizer and get back to real size.

Yeah, I think we should have a new motto: "Only one shark attack per day."

I'’’m with you, bro.

Let'’’s get out of here before that tiger shark comes back.

Wow, these turtle flipper attachments are amazing.

Oh yeah, I can'’’t wait to see them in action.

Well, you don'’’t have to wait long.

Do you have the master key Jimmy?

Right here.

Well, start her up!

Let'’’s bring the Tortuga back online.

I'’’m on it.

ALL: No!

That'’’s our only master key!

What?!

We don'’’t have a spare?

No!

Oops, sorry.

There, it landed somewhere near that big brain coral.

I'’’ve got to go in and get it.

No way.

Look!

The tiger shark!

But guys, the Tortuga can'’’t drive.

It can only float here without that master key.

You'’’ve got to get down there and get it.

What?!

Did you see that tiger shark?

Yeah, we'’’re sticking by our new motto: "Only one shark attack per day."

No exceptions.

What if I program you a Sea Turtle Power Suit?

That'’’ll give you protection.

Okay, maybe one exception.

Okay, the essential sea turtle powers are: streamlined shell; long front flippers for flying through the water; short rear flippers for steering; oxygen intake mechanism that gives the bros 10 minutes of breath capacity; and cutting beak capabilities for eating sponges... in case the bros get hungry.

Sea turtle power disc programming complete!

First, we'’’ve got to find Shield!

Touch him and activate our sea turtle powers!

Don'’’t dive now!

There he is!

Dive now!

Activate Sea Turtle Powers!

Okay, let'’’s go find that master key.

It fell somewhere near that giant brain coral.

Keep your eyes peeled for that tiger shark.

Look!

The key landed here, but then disappeared.

Check it out, Chris.

Tracks of a crab or lobster or something.

It walked right by the key.

Maybe it picked it up.

Why would a crab or lobster pick up a key?

And how?

I don'’’t know, but it'’’s the only lead we'’’ve got.

Come on!

Let'’’s follow these tracks!

CHRIS: Looks like a lobster to me.

MARTIN: Nah.

I'’’m going with the big old crab.

Lobster.

Crab.

There it is!

Yeah, it'’’s a crab-- a spiny crab.

But big as a lobster!

And she has the master key!

Tiger shark!

And we look exactly like his favorite prey!

Take evasive maneuvers!

With you, bro!

I'’’ll lead him away.

And I'’’ll get the master key!

All right, I'’’ll just grab the key... Oh no, I don'’’t have hands-- I have flippers!

How am I going to grab the key?

I don'’’t know, bro, but figure it out fast.

I can'’’t shake this shark!

Aah... shield defense!

This shark is hungry.

Hurry, bro!

Chris!

You'’’re lucky that we modeled the suit on the hawksbill turtle.

They have two claws on their flippers.

Check it out.

Oh yeah...

The hawksbill doesn'’’t use them for much, but you can.

I'’’ll use them to hook the bungee of the master key.

Got it!

Martin, I have the key.

Meet you at the Tortuga!

I'’’ll be there bro, just as soon as I get this tiger shark off my back.

Oh!

Whew!

Hey, let'’’s get out of here, bro!

Yeah, two shark attacks is way too much for one day.

Hey, check it out!

There is such a thing as flying turtles!

Anybody looking for the master key to the Tortuga?

JIMMY: Tortuga online.

Okay Jimmy, let'’’s take her for a test drive!

Diving.

It'’’s working.

(Cheering) Yeah, sea turtle mode is the best.

I wonder what Shield thinks.

Uh, that this is the biggest sea turtle he'’’s ever seen.

And the new Tortuga swim mode is really going to help us explore the oceans of the world.

And meet all kinds of new creatures.

Hey, we'’’ve arrived at a habitat that is ideal for the green sea turtle.

In the water below is a grass flat that is full of the green turtle'’’s favorite food.

BOTH: Sea grass!

Come on, let'’’s check it out.

Adult green sea turtles, unlike most sea turtles, love to eat sea grasses and algae, so the grass flats are a great place to find them.

CHRIS: And other creatures.

A hermit crab!

MARTIN: Drum fish!

CHRIS: Trigger fish!

MARTIN: Blowfish!

All living off the sea grasses.

CHRIS: And a spotted eagle ray!

Wow, look at him flying!

Martin, over here!

What?

CHRIS: A green sea turtle!

MARTIN: Oh yeah... Hey, he'’’s got that shield defense working.

Did you see that?

That is the sea turtle'’’s defense in action.

Using that shell to protect itself when it'’’s a little unsure, the sea turtles turns away, keeps an eye on you, swims this way, keeping the shell as a shield towards whatever it'’’s wondering about.

In this case, us, but in most cases, sharks.

CHRIS: But green turtles aren'’’t the only sea turtles.

You never really know what species of sea turtle you'’’re going to bump into.

There are hawksbill turtles, named after their hawk-like beak.

MARTIN: Or the Loggerhead turtle.

The Olive Ridley is the smallest of sea turtle species: less than three feet long.

But all these sea turtles have similar body designs: the shell, the strong flippers to propel them through the water, and big lungs to hold their breath for a long time.

And overall, a streamlined body that makes them perfectly designed for life at sea.

CHRIS: Another thing they have in common, besides their body design, is that they'’’re all in danger.

And the biggest threat facing the sea turtle'’’s future survival, is the changes humans are making to the seas.

People who love sea turtles are the ones who can keep them around, from the time of the dinosaurs, to way into the future.

So keep on creature adventuring.

We'’’ll see you on the creature trail.
