♪ Wild Kratts ♪ CHRIS: We’re here in North America!

MARTIN: Down here in the Southwest, in a spectacular wildlife habitat known as the Sonoran Desert.

CHRIS: A rough, hot and dry landscape where it can be nice to have horses to help you get around.

MARTIN: It’s us, the Kratt brothers!

I’m Martin-- CHRIS: I’m Chris!

And we’re looking for rattlesnakes!

Our horses have taken us out into rattlesnake country.

And since horses don’t really like finding rattlesnakes, we are gonna take it on foot from here.

♪ Hang tight, guys.

So, where do you find a rattlesnake?

Some good places to look-- under a cactus.

All clear.

Or around a pile of rocks.

Hey, rattlesnake?

Anybody in here?

Nope.

But sometimes, the best way to find a rattlesnake is just to wander around-- (Rattling) until a rattlesnake tells you where he is with his rattle!

Oh, here he is!

A western diamondback rattlesnake!

MARTIN: And with that rattle, he’s saying, "Watch out!

I’m here!"

So nobody steps on him, nobody bothers him.

CHRIS: Looks like he’s about four feet long, and they get over five feet.

So, this is a pretty big guy.

See how his neck and head are raised like this?

That’s the strike position, so he’s ready to defend himself.

But first, he rattles that warning!

Wow, a western diamondback rattlesnake in the Sonoran Desert!

Yeah!

This is one of my favorite animals.

Yeah, and a rattlesnake has some amazing creature powers.

A rattle warning.

A venomous bite.

Heat vision!

And more!

Imagine if you could have rattlesnake powers.

BOTH: What if?

We have been rocking ’round the creature world and have hit all sorts of great habitats and met hundreds of amazing creatures.

But we’ve only scratched the Earth’s surface.

There’s still hundreds of habitats left to explore!

And millions of new creatures to meet.

The question is, where do you want to go first?

We could do lots more on my favorite continent: South America.

Maybe the Pantanal of Brazil?

I’d kind of rather go back to some kind of safe little forest in Australia.

And meet some soft and cuddlies like wallabies and wombats.

And don’t forget the 100 species of venomous snakes and spiders that live in Australia.

Euch!

How about Asia?

There is so much going on in this massive continent.

I could really go for the bamboo forests of the giant panda.

Or, we could hit some more habitats in Africa.

We’ve adventured through just small parts of the Savannah.

And what about other habitats?

Like the mysterious jungles of the Congo?

You know, I’m dying to go down to the bottom of the Earth to Antarctica-- the icy home of animals like emperor penguins and leopard seals!

Oh, planet Earth has so many awesome habitats!

How are we gonna decide where to-- (Crashing) ALL: Whoa!

Uh-oh!

The Tortuga is seizing up!

We’re losing altitude!

We’re going down!

To somewhere in North America!

But where in North America?

There are so many habitats we haven’t explored yet here, either.

Well, we’re gonna find out soon!

Prepare for a crash landing!

Oh, wow!

This is good.

How is this good?

We’re going down for a crash landing!

Yeah, but look where we’re gonna crash.

(All screaming) Hang on, everybody.

It’s not gonna be one of my usual silky smooth landings!

(All screaming) ALL: Oomph!

(All shouting) (All sighing) Aah!

(All groaning) Awesome landing!

Check it out, Chris!

The Tortuga decided that our next adventure will be-- BOTH: The Sonoran Desert!

Oh, yeah!

We totally forgot about this.

But the Sonoran Desert is one of the coolest places on the planet.

Think about all the creatures who live here.

Rattlesnakes!

Roadrunners!

Javelinas!

Coyotes!

Elf owls!

Gila monsters!

Jaguars!

Ringtail cats!

Don’t get too excited yet.

We’ve got a major problem here.

And I mean major!

(Both gasping) Oh, no!

It’s even worse than I feared!

What, Koki?

What is going on?

The Tortuga is dying.

ALL: What?!

What do you mean, "dying"?

Well, you know how tellurium crystals are essential for all of the Tortuga’s functions?

Semi-conduction of the power systems, navigation systems, computer systems and particularly the power function of the Creature Power Disc press?

ALL: Mm-hmm.

Well, the tellurium crystals are failing.

(Gasping) Soon, they will be completely spent!

(Rattling) Looks like some already are!

We need tellurium for the Tortuga to work.

If the tellurium crystals burn out completely, we won’t be able to bring the Tortuga back online!

Ever!

Wait, this is easy.

We’ll just get a new supply of tellurium.

Not easy.

Tellurium-- (Buzzing) Tellurium is a metalloid that is in very short supply.

In fact, there’s more of it in outer space than there is here on Earth!

And it’s even more rare than platinum.

This means that unless we find some more of this precious tellurium, my inventing days on the Tortuga are over!

And that means our adventuring with Creature Power days would be over, too!

Koki, is tellurium found in the Sonoran Desert?

Well, it could occur in small amounts anywhere on Earth.

It’s extremely rare.

The trick is finding it.

(Horses whinnying) (In southern accent): We’ll find us some tellurium in no time!

Quicker than a horse can crunch a sugar cube.

Wait, we have no communication system!

Only the Creature Pod, and it’s only at half power.

So it’s gonna be trickier for us to keep in contact.

Don’t worry!

This won’t take us long at all.

It’s so shiny, it’ll be easy to spot.

♪ Alright, as soon as we spot something shiny in the ground then that’s where we’ll start to dig.

(Gasping) ♪ (Gasping) Hey, do you ever get the feeling that these cactus are watching you?

No, are you kidding me?

Why?

Because that one has eyes.

(Chirping) (Laughing) Oh, an elf owl!

Come on, bro, we gotta check him out.

That’s gonna have to be another adventure, bro.

We have to find the tellurium.

The future of the Tortuga depends on it!

Oh, yeah, yeah, you’re right.

We’ll come back for you someday, elf owl!

♪ (Howling) Oh, wow!

A coyote!

The most adaptable of all North American animals.

Maybe he’s standing on some tellurium.

Let’s go up there.

Nice try, bro.

But you know that minerals are not likely to be found on mountain peaks.

We gotta be looking on the ground.

Look, a lizard!

Being chased by a roadrunner!

A real, actual, real-life roadrunner!

Yee-haw!

Ugh, we’ve got to stay on our tellurium crystal finding mission!

Hang on there, bro!

Wait up, roadrunner!

Aah!

Ooh!

Roadrunner!

Come on, Martin, don’t get distracted.

We’re chasing tellurium, not roadrunners.

(Gasping) Spotted skunk!

Aww!

Oh, Gila monster!

(Crying) ♪ JIMMY: Come on!

My controller has nothing to connect with.

It can’t do anything!

Humph!

(Sighing) So, what do you think, Koki?

Well, I think the guys don’t have much time to find some tellurium crystals.

The core of the Tortuga powered by the tellurium crystals will go into an irreversible shutdown in three hours!

Oh, no!

(Beeping) Calling Kratt bros!

CHRIS: Yeah, Aviva, go!

You only have-- (Static buzzing) Pardon?

Hey, Aviva?

Wait, there’s no video!

AVIVA: I know, we have to conserve power.

Listen up-- you only have three hours.

(Both gasping) Yeah, three hours to get back here with some tellurium.

(Engine struggling) And if we use any of the Tortuga’s abilities like the teleporter or the Creature Power Press, each use will cut the core’s life and your time to find tellurium crystals in half!

Find the tellurium-- And find it fast.

BOTH: Got it!

(Rattling) BOTH: Whoa!

(Rattling) BOTH: Whoa!

Um, Martin?

So, what do you do when you’re face-to-face with a venomous rattlesnake with one inch fangs that can strike in the blink of an eye and is attracted to movement?

Don’t move, bro.

(Rattling) See ya!

Ha!

Phew!

Now that was a close-up look at one awesome snake!

You can say that again!

How about that rattle?

It’s made of special loose scales that rub up against each other to make that rattling sound.

And it’s that rattle that makes the rattlesnake the most polite snake!

Polite?

How is a rattlesnake polite?

Well, he always rattles you a friendly warning before he strikes and sinks his venom-injecting fangs into your arm.

Or your face.

And you know, when I was face-to-face with this guy, I had a real-close look at how his face is packed with incredible sensory powers.

Sharp eyes that can see well in the daylight.

Nostrils that have a good sense of smell.

And a tongue that flicks in and out, tasting the air, making that good sense of smell great.

Plus, there’s another sense that-- huh?

What was that?

Oh, he seems to know.

And wants to get closer to it.

But if we can’t see it, how can he?

He must be using the other sensory organ-- those pits right under his nostrils.

Those pits that sense the body heat of animals!

Those pits that give the rattlesnake the ability to see heat and find his prey.

Like a ground squirrel!

He knew that’s what it was because a rattlesnake can see heat.

And so can we.

With our heat vision goggles!

Nice!

Turning on.

Hi, Chris!

Do you see me?

Oh yeah, Martin.

You’re waving?

Okay, then now what am I doing?

CHRIS: You just jumped into a ninja pose.

(Chuckling) Okay, my turn.

Turning on!

Huh?

Oops!

I think I have these goggles on upside down.

CHRIS: Nope, they’re on right!

I’m doing a handstand!

Now what am I doing?

MARTIN: You’re walking like an Egyptian.

CHRIS: You got it!

Hoo hoo, yeah!

Ho ho, yeah!

Hey, look!

(Gasping) ♪ Huh?

They went in there.

I know!

Let’s get around underground the way a rattlesnake does!

By going through the ground squirrel tunnels.

We don’t even have to dig.

I bet those tunnels will lead us right to some tellurium somewhere down there.

We can see with our heat vision goggles.

Miniaturization, anyone?

Whoa!

♪ Rattlesnake!

There he goes.

Let’s go!

It’s kind of weird not having Aviva and the gang checking in on us all the time.

Yeah, kind of weird.

(Beeping) Alright, I’ve turned everything off I can think of.

Okay, then.

We’re in emergency power saving mode.

And the tellurium core is on life support.

We only have enough power for either one Creature Power Disc creation, maybe half a Miniaturizer recharge or one teleportation of an object.

But only one choice and not all!

Let’s see how the guys are doing with their search for tellurium crystals.

MARTIN: Hello?

Hello?

(Static buzzing) What in the world?

Where on Earth are you guys?

In Earth, actually.

Yeah, we’re taking a new approach to our tellurium search.

We’re seeing with heat vision and walking around through the tunnels of ground squirrels, walking behind a rattlesnake and-- whoa!

Oomph!

Uh, the only problem is pebbles on the ground don’t give off heat.

So, we can’t really see ’em with heat seeing goggles on.

Wait a sec, if we can’t see the pebbles that are tripping us, then we won’t be able to see the tellurium crystals, either!

We need to see with heat and with our eyes.

Uh, Aviva?

We need Rattlesnake Power suits.

That would not be a good idea.

Creating one Power Disc would suck up the remaining power.

And remember, tellurium is very rare.

Even with Rattlesnake Powers, there’s no guarantee you’ll find it.

Oh, but ground squirrel burrows are extensive in the Sonoran Desert.

Alone, they cover thousands and thousands of square miles.

Of course we’ll find tellurium.

(Alarm blaring) (Sparking, buzzing) And we’ve got to do something.

If we don’t find tellurium, the power core will fade out in just two hours anyway.

We’ve got to try.

We do kind of have to try.

We’ve gotta try!

I’m gonna start modifying the Eyelash Viper Disc with Rattlesnake Powers.

♪ MARTIN: Yeah, these rattlesnakes’ long, thin body design lets them go anywhere in the ground squirrel tunnels.

He’s just looking for a spot to set up an ambush.

Jimmy, catch!

Energize and-- Jimmy, no!

Sorry!

I forgot!

(Alarm blaring) We’ve got 30 minutes!

And then an irreversible meltdown begins.

The Tortuga will be totally dead.

But then how are we gonna get the miniaturized Rattlesnake Power Discs to the Kratt brothers so they can find the tellurium?

Jimmy, you’ll have to deliver them by hand.

What?!

(Shuddering) He looks snake bit.

Maybe that’s what he’s worried about.

Jimmy, it’s your job to teleport the discs.

And we can’t do that now, so you’ve got to hand deliver them.
