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

MARTIN: In the Caribbean Sea.

Hey, it’s us, the Kratt brothers.

I’m Martin.

I’m Chris.

A healthy coral reef is full of all sorts of creatures: millions of colorful fishes-- Lots of corals and sponges-- All kinds of other creatures, from sea turtles to dolphins.

And today, we’re looking for a certain kind of very unusual coral reef fish.

And this one is a great hider.

But he’s also one of the fastest striking predators in the sea.

So look out.

Let’s go!

♪ The rocky-looking stuff around us is coral.

Then there are sponges and-- Whoa, there’s a hiding creature, a moray eel, waiting in ambush.

But he’s not the fish we’re looking for.

I wonder where he’s hiding?

There’s another great hider right here.

Do you see him?

A flounder!

See his mouth opening?

He’s almost invisible against the sand.

But still no sign of him.

Wait, down there, our mystery fish.

See him?

We found one!

The creature we’re looking for is down there resting amongst all those sponges.

See if you can find him.

MARTIN: A frogfish!

Do you see it?

The frogfish camouflages himself to look exactly like his surroundings.

Amazing.

This is one strange fish.

Imagine if we could get to know this very strange reef creature.

And experience his incredible creature powers of stealth and speed.

What if?

What if?

Oh yeah.

Night time is the best time.

It’s the only time to see them.

Yeah, well, who’s "Them"?

I mean, maybe we don’t really want to see them.

They’re only some of the most important creatures on the planet.

AVIVA: Who, us?

Aww.

Thanks, guys.

Jimmy, the creatures we’re heading down there for are very strange sea creatures that built the coral reef.

A creature makes that?

I thought it was rocks and stuff.

No way.

It all comes from an animal, a special animal that hides out during the day.

But at night, under the cover of darkness, they come out.

And they build-- Bit by bit, higher and higher, the reef rises, so big it’s the largest living structure in the world.

But by dawn, when the sun rises, they go back into hiding, gone, like they were never here.

Okay, are you trying to freak me out?

’Cause it’s working.

It’s exciting, Jimmy!

AVIVA: I’ll say!

I thought we were going down to do a check-up on reef health for the World Reef Science Team.

But who are these creatures?

And how come no one ever told me about them?

What are they called?

Polyps.

Polyps.

Polyps?

Polyps.

Polyps.

See you.

See you.

Huh, what a funny name.

This should be a good spot to find them, Martin.

Oh yeah.

Oh, I hope we got here in time.

Yeah, they should be coming out right about now.

Hmm.

No sign of them yet.

So now, we wait.

Look, they’re coming out!

Whoa, ho!

Polyps!

They’re everywhere!

Wow!

They’re beautiful.

You mean these colorful things are creatures?

They look like flowers.

Oh yeah, they’re animals all right.

Every one of them is a creature.

And check it out.

The hard rocky part is their skeleton.

See, they build a skeleton outside their bodies and they can hide inside it, protected, until they’re ready to come out.

You mean this whole reef is made of the skeletons of these little guys?

That’s right: polyp skeleton, built on polyp skeleton, built on more polyp skeletons for millions of years.

And now millions of creatures live here, in and amongst the coral, more different types of sea creatures than any other ocean habitat.

Yeah, but we know these reefs are fragile habitats.

And if we’re going to do our annual reef check-up, to make sure it’s healthy, we’d better get to it.

Okay, let’s get in there for a close look, guys.

On it.

Ah!

Ah, wha... Ah, ooh, ah.

Close enough?

Ooh!

Oh, bro, you just got harpooned.

AVIVA: What?

"Harpooned"?

You have to zoom in with a microscope to see it, but the polyp shot that tiny needle-like harpoon from his tentacle.

That’s how they hunt for food.

Hey, what’re you harpooning me for?

I’m not food.

Ah, here comes some stuff that’s probably tastier than you.

Ultra zoom on.

That’s what they love to eat: amphipods!

And see?

There are the harpoons, ready for launch.

Ooh, he did it.

He scored some lunch.

He reels it in with his harpoon and the tentacles push the little meal to his mouth, right down there in the center.

Wow!

I like these little guys.

And all this time, I thought coral was just a bunch of rocks.

KOKI: Hey!

What are you doing?

Leave that coral alone!

Those fish are destroying the reef!

So, that’s why the coral reefs are disappearing, those reef-eating fish.

Whoa, not so fast.

They’re parrotfish, Aviva.

And they’re not why the reefs are in trouble.

Check it out.

He’s scraping algae off the coral with his hard beak and eating it.

And he does kill and even eat some polyps while he’s at it.

But he’s also keeping the algae from taking over and choking out the reef.

Hmm!

Hmm!

(Beeping) So, you see, it’s all balanced.

Parrotfish are part of a healthy reef.

Okay, that’s good, because coral reefs have enough problems with pollution and stuff without any new dangers popping up.

That’s right.

After all, a lot of creatures depend on these guys.

Without them, the reef wouldn’t even exist.

(Beeping) See?

(Laughing) I told you it would work.

My robotic programming makes this fish do whatever I want.

I send him out to fetch coral and he brings it back to me.

Yes, good work, fish dog.

"Fish dog"?

Him.

Oh, yeah, that’s right, him.

Now give me the coral.

Ah, yes.

If I dry this out and polish it up, I could make a gorgeous necklace.

And sell it.

Or some earrings.

And sell them.

Or maybe a belt buckle.

And sell that too, and I get rich!

You mean "We".

We both get rich, remember?

You collect the coral with those robot fish, I make the jewellery, 50/50 partners.

Deal?

Ugh, don’t you endangered animal fashion designers trust anybody?

Fine.

Deal.

Okay, Zach-bots, our test run worked.

And with these fishies doing our coral collecting for us, no one will ever know it’s us that took it.

(Laughing) All these fish are working for us now.

Fit them with my robotic vests and brain caps.

Let’s roll!

No, not literally.

I meant "Get going."

Move!

Move!

(Chuckling) Just a little glitch.

Soon, we will have coral, Donita, lots of it.

Oh, but Zach, don’t you mean-- All of it!

All of it!

Yes, all the coral in the sea will be ours!

(Laughing) Okay, so last night, we figured out that this area of the reef is looking good: healthy coral, water pollution low, stable temperatures.

Now, all we have to do is finish our fish survey.

And then we’ll go and do a check-up on a different part of the reef.

I love being a coral reef doctor.

All part of being the Wild Kratts crew.

Hey, JZ, did the guys start the survey?

Yeah, and I’m helping lure in some fish.

Really?

How?

With this!

Here, fishy, fishy, fishy, fishy!

Don’t be fooled by that trick, buddy.

Things aren’t always what they seem.

Plastic.

AVIVA: Guys, you down there?

Roger that, Tortuga.

We’re just finishing up.

Found a whopping 213 different species of sea creature living in this small area of reef.

Yeah, but I think we counted all of them now.

They don’t call me "Fish Finder Marty" for nothing.

Who calls you that?

Oh, I do, sometimes.

We’ll be topside in a-- Uhh, guys, coral doesn’t walk, does it?

No.

It doesn’t move at all.

You sure it doesn’t walk?

Walking?

Now that would be a real trick.

Ha, walking coral, imagine that.

You don’t have to imagine it.

Just turn around.

What?

It’s... It’s impossible!

It’s unbelievable!

It’s... A frogfish!

A frogfish!

What?

A who?

A frogfish.

It’s not coral.

It’s a fish pretending to be coral.

Things aren’t always what they seem.

Aviva, make that 213 plus 1 different creatures on this part of the reef.

Oh, what a strange guy.

Hey, he actually walks on his fins.

I got to film this guy.

But what’s with the camouflage anyway?

Why is he pretending to be coral?

No, wait.

Don’t poke around there.

It’s not coral.

It’s a giant mouth!

Whoa!

Did you see that?

See what?

Did you blink?

Maybe.

I might have.

Then you missed it.

Missed what?

Hey, where’d that snapper go?

Rocket Jaw over here-- Can I call you Rocket Jaw?

Well, he kind of, well, made him disappear.

Oh, now he’s a magician?

Yeah, sort of.

He swallowed him, whole!

AVIVA: That’s impossible!

That snapper was huge.

Besides, he was here a second ago.

I blinked and he was gone.

Yeah, that’s all it took.

Hey, my Creature Pod was still on record.

Maybe it’s captured here.

Up-linking video feed.

Hmm, a bunch of coral, more coral.

Wait!

There!

Go back.

(Rewinding) Rocket Jaw rocks!

You’re not kidding.

That was six milliseconds!

Let’s see that in slow motion.

Wow.

The mouth is faster than the eye.

I don’t believe it.

That gape-and-suck trick is the fastest attack of any animal.

I’ve got to match that speed.

Muscles can’t even twitch at six milliseconds.

By suddenly widening her mouth twelve times bigger than usual, she makes a suction that pulls the water and fish towards her.

So, not only does she lunge her jaws forward at lightning speed, but also sucks the fish towards her mouth at the same time!

And with that huge mouth and giant stomach, she can even swallow things twice her size.

Guess what, guys.

You got to make a Power Disc?

I gotta!

I thought so.

Mm-hmm.

DONITA: Ugh, your surroundings are very uncomfortable and, well, grey, Zach.

I’m glad I had Dabio drop me off with my chaise longue.

Hey!

I like grey.

It’s very, uhh, grey.

Huh?

Well, I want the colorful corals: pinks, yellows, reds.

I’ll need lots of them, Zach.

My line of coral rings, earrings and necklaces will be the talk of the town, not to mention my coral encrusted shoes, belts, gowns and swimwear.

Oh, what good is coral in the sea when it’ll look much better on me?

There, that’s the last one.

My coral-collecting robotic fish are complete!

Now, I simply activate the fetch command and homing feature and these nice little guppies will bring me coral until there is no coral left to bring!

They’re guppies?

Something like that, guppies, goldfish, whatever.

Oh, who cares?

Let’s get them going, Zach.

Guppies, fetch!

And now, for my greatest act of all time, I too will disappear into the reef, frogfish style.

Huh?

Whoa!

What?

Martin?

Well, he did disappear.

Ta-da?

Ooh.

Hey, what’s with those fish?

They’re breaking off huge chunks of the reef!

I’ve never seen that kind of parrotfish before!

At that rate, they’ll destroy the whole reef.

I mean, reefs only grow 5’ every 100 years.

Once it’s destroyed, it may never have a chance to grow back.

We need to get a closer look at those guys.

(Beeping) Look, that one doesn’t see Rocket Jaw.

(Beeping) Whoa!

Gone!

Well, that’s one way to protect the reef.

Huh?

(Clattering) Is something wrong?

Hey, this fish has a weird platinum vest.

Zach Varmitech!

Zach Varmitech!

He’s controlling these poor parrotfish, having them destroy the reef!

But why?

I don’t know.

But we’ve got to stop them, and fast!

(Grunting) But how?

They’re too quick!

Like the reefs aren’t in enough trouble already.

Now they have Zach messing with them!

That may be true.

But we have Rocket Jaw and his frogfish powers on our side.

Power Disc Actualizer on!

All set.

Guys, get ready to catch robot fish, frogfish style!

Jimmy!

Zap it!

Ha!

Activate Frogfish Powers!

Activate Frogfish Powers!

♪ Yes, the old frogfish color change trick.

Let’s go camo.

Okay, now this is my disappearing act.

Okay, parrotfish, bet you can’t see us.

(Beeping) Gotcha!

Yeah!

It’s working, Chris!

And just like a real frogfish, we can grab them so quickly that the rest of the school doesn’t even notice they’re missing.

Let’s fill ’er up.

(Beeping) CHRIS: Okay, Jimmy, bring ’em up.

Don’t worry, little parrotfish.

We’ll get you free in no time.

Coming down.

Nice work, JZ.

Righty-o!

(Beeping) Six milliseconds!

Ha!

This is so easy with frogfish power.

Yeah, we’ll have this taken care of in no time.

DONITA: Where are they, Zach?

Uh-oh!

Donita!

Zach!

Not now.

Hide!

We’re already hiding!

Oh yeah.

ZACH: Like I said, I don’t know why they’re not all coming back, Donita.

See, these ones are working fine.

Pause.

Let’s see over here.

There are one, two, three, four, five, five fully functioning Varmitech robots right here.

Uhh, Zach, that’s four, four fish, not five.

What?

There were five!

Hey, something’s fishy here.

Fish, Zach, fish are fishy.

AVIVA: Chris, Martin, there’s a problem.

We can’t free the fish.

The robotic gear is locked on and can only be deactivated with Zach’s controller.

We need that remote.

You have to get Zach’s remote.

We’d have to sneak up on him or something.

Hey, cut that out, Rocket Jaw.

We’ve got to think here.

Wait a second.

That’s another trick!

Frogfish don’t only pretend to be coral.

He actively lures his prey closer with that make-believe shrimp.

He fishes for his prey!

Check it out.

Rocket Jaw wiggles that special spine to make it seem alive.

The fish moves closer, and closer.

Whoa!

Whoa!

What was that?

Ah.

(Gasping) Oh, good little guppy.

Keep up the good work.

Aviva, a lure attachment, we need a frogfish lure attachment for our suits.

We’re on it, guys, one that’ll lure in Zach and Donita, coming up!

Eight, nine.

No, wait.

I counted you.

Uhh, nine, eleven.

Oh, forget it!

Zach-bots, listen up!

Make more of those robot guppies, as many as you can.

And just keep them coming.

There, problem solved.

Now let’s get back to making-- Ooh!

Ooh!

Ooh!

Ooh-hoo-hoo-hoo-hoo-hoo-hoo-hoo!

Money, treasure!

Ooh, with my picture on it.

Zach?

Zach, what is wrong with you?

Ooh!

Beautiful, sparkly coral jewel, I must have it.

It’s working, guys!

All you need is the right lure.

You sure are a master of disguise, Rocket Jaw.

Varmitech gold.

One-of-a-kind Donita jewel.

Now!

Now!

Huh?

Huh?

My aquajet, where’d it go?

It disappeared.

Mine too, vanished into thin air.

Water, Donita, vanished into thin water.

Where are they?

Why’s everything disappearing around here?

Hey, my remote!

(Laughing) Good one, Rocket Jaw!

The mouth is faster than the eye.

Oh, those Wild Ratts!

Where are they?

And who’s Rocket Jaw?

We’re right here, behind you.

Very funny.

Is this some kind of magic trick?

Give me back my remote!

Hey, Zach: ta-da!

Huh?

Ah!

Ah!

Ah!

No way.

We need it to free those parrotfish, Zach.

Then you can have it back.

Hmph.

Ugh.

That’s right.

It’s not nice what you’re doing to them.

And, not only that, the coral is a living creature.

You can’t just bust it up and destroy it.

You’re not only hurting the coral polyps, but the millions of sea creatures that live here.

Right, Rocket Jaw?

Who cares?

We don’t even know what a polyp is.

Check it out.

They’re the creatures all around you and-- I don’t care.

Yeah, so give us the remote.

Okay, but not until those parrotfish and polyps are free.

DONITA: Ah!

ZACH: Stop!

My guppies!

Ugh.

Ha!

You’re free!

Okay, Aviva, control systems are shut down.

Great, guys, just in time.

Freeing those polyps now!

They’re still alive and well.

But we don’t have much time.

Let’s get you polyps home!

Now you can have your remote back, Zach.

Hmph!

Oh, and we almost forgot: your aquajets too.

Huh?

Huh?

Ah!

We’ll get you Wild Ratts!

Ah!

That’s Wild Kratts!

That’s Wild Kratts!

With frogfish power!

That’s the last one.

Okay, coral polyps, you’re back home.

This special coral polymer adhesive you invented really works great, Aviva.

There, all set!

Mission accomplished.

This part of the reef is back and healthy again.

And we can move on to do a check-up on another part of the coral reef.

Thanks, Rocket Jaw, for showing us your awesome powers of disguise and trickery.

Yeah, and a six millisecond strike?

That’s unmatched in the creature world.

Remember, things aren’t always what they seem when a frogfish is around.

(Gasping) AVIVA: Mmm.

Anybody hungry?

Looks like Jimmy’s luring us up for dinner.

Oh, that one’s mine!

Ah!

No way!

I got it!

Not before us!

(Laughing) So, frogfish are one of the strange and special creatures that make their home on the coral reef.

So, let’s get back down there and check out each amazing feature that makes the frogfish such an incredible fish hunter.

Ready, Chris?

Ready.

First, we have to find him.

Hopefully, he’s in the same spot.

Oh!

Here’s a piece of coral with polyps out.

See, there are millions of polyps, little tentacled creatures that make up the reef.

Ah, a parrotfish, a princess parrotfish.

She’s eating some algae off the corals and sponges.

It’s all part of a healthy reef.

And there he is, still in the same spot.

The frogfish!

So, the first feature is that camouflage skin.

He changes color to match that little piece of sponge exactly.

It’s almost impossible to tell.

Even his body shape is kind of blobby.

He’s also very patient and will wait completely motionless for an unsuspecting fish to come close by.

If that doesn’t work, then there’s the lure.

The frogfish can make his prey come to him with a built-in fishing pole, at the end of which is a lure that looks just like a tasty shrimp.

The frogfish waves it around.

The fish comes closer, closer.

He waits.

Ooh, he gets it!

One of the fastest strikes in the creature world.

How can a frogfish do that?

Well, it’s all in the mouth.

That mouth opens almost instantly, creating the suction he needs for the strike.

All right, we’ll see you later, buddy, so we don’t blow your cover.

From coral polyps to parrotfish-- To frogfish and beyond, coral reefs and the creatures who live there are incredible.

Keep on creature adventuring.

We’ll see you on the creature trail.
