♪ Wild Kratts ♪ - [Chris] On the continent of Asia.

- [Martin] In the southern region.

- [Chris] Amongst the forest and grasses, slithers the King of Snakes.

The King Cobra.

Hey!

It's us, the Kratt Brothers.

I'm Chris.

- I'm Martin.

People are fascinated by venomous snakes.

Like cobras, rattlers, and mambas.

These kinds of snakes can inject deadly venom into their enemies or prey.

A venom strong enough to kill other animals sometimes in a matter of seconds.

- Let's take a look at a couple of them.

- This is a Brazilian Smooth Snake.

It's sometimes also called a False Water Cobra.

This snake is venomous, but it's not a true cobra.

It's called a False Water Cobra because this snake can flatten the skin around its neck to make it look bigger to any dangerous animal that is near.

True cobras have taken this cool trick to a whole other level.

- Like the one we found in Southeast Asia.

This right here is the king of all snakes, the King Cobra.

This is not only the largest cobra in the world, but it's also the longest venomous snake on the planet.

It can reach lengths of 18 feet long.

Now remember, Martin and I are zoologists, experts at being around venomous snakes.

Never approach a venomous snake and always back off.

Awesome.

- Imagine if we could understand how the King Cobra lives and how he uses his impressive venomous powers.

- Imagine if we had King Cobra power!

- [Both] What if!

- [Chris] Yep, looks like it.

- I remember passing that log before.

- Was there an Indian Mongoose on it last time too?

- What mongoose?

- He was just there!

Man, they're fast, zippy creatures.

- Let's find him.

- Whoa, bro.

Not til we find your lost Creaturepod.

It's only the most important adventure gadget ever.

- Oh yeah, My lost Creaturepod.

Right.

So you still got a signal on it?

- Yeah, that way!

- [Martin] My Creaturepod.

Here we come!

- You really got to be more organized, bro.

Take it from me, The Organization King.

- Yeah, but every time I try to put something somewhere that I won't lose it, I forget where I put it.

Like last week, I had this great sandwich, but wanted to save half for later.

I still don't know where I put it.

(sniffs) I do.

(coughs) - Oh yeah.

See, when I try putting things in your organization system, it doesn't work.

- Oh, brother.

- Well, I don't really want it now.

- Okay, it says we're close.

Should be right around here.

(gasps) Oh, hello.

(gulps) large, venomous Spectacled Cobra.

Um, nice bumping into you like this or not.

- Can you grab it, Chris?

- The snake?

No way!

- No, my Creaturepod.

- Are you crazy!

I can't make any sudden movements here.

- Yeah.

It's the classic cobra defensive pose, with that awesome hood.

He's saying, "I'm scared and I really don't want to bite you, but I will if I have to."

- Message received, buddy, I'm backing off right away.

- Hmm, Hoodie!

That's what I'll name him.

- That's great, but I really don't want to have a staring contest with a Spectacled Cobra.

- I'll pull ya outta there real easy.

- [Aviva] Hey Guys!

- I win now!

- [Both] Whoa!

Oof.

- Whew, thanks bro.

- No problem.

But he's still got my Creaturepod.

- Guys?

Hello?

- We've got a little problem with a cobra.

- But nothing we can't handle.

- Ugh, sorry, not helping with that.

- Cobra!

Cool!

I love cobras!

A creature that has venom or toxin in their teeth.

And look at that hood!

- We got an X-ray scan of it.

Check it out.

These ribs have a special way of moving out and back, which opens the hood wide.

It's a defensive posture.

- Excellent!

I can use that for the Cobra Creature Power Suit!

Find out how the venom works please!

- Find out how the venom works?

- Uh, glad to see she's so concerned about our predicament.

- Chris, look!

- Now that is the hunting posture.

Just a little hood.

- Can you synchronize the Creaturepods?

- Tapping into the scanner.

- Wow.

That is serious venomous strike power.

- One bite and it's over.

Check it out.

When the snake strikes, the venom travels from this gland right through the hollow fangs and is injected into the frog.

That's how the venom gets into the prey.

- Whoa!

And it's a neurotoxic venom!

Oh quick.

Zoom in to the nerves.

The nerves are like telephone lines, carrying messages from the brain, telling muscles like the heart to beat.

The messages sometimes need to jump from one nerve to another with the help of these molecules that carry the message to the other side.

So things like the heart keep working.

- But look!

The cobra venom!

It's getting in the way!

Now when a message comes down.

It can't get through because the venom molecules are clogging the receptors.

Without those messages getting through, heartbeat, breathing, it all stops.

- And the cobra gets his meal.

Aviva, we found out how the venom works.

- Awesome.

Send me the info and I'll use it in the suits.

Good luck getting that Creaturepod.

- Chris, look!

That Indian Mongoose is back.

Hey.

Are you thinking what I'm thinking?

- Oh yeah, I'm thinking what you're thinking.

- [Both] Venom Immunity!

- The mongoose has it!

We got to stick with him.

Find out his secret.

- And there's one good way to do that!

- [Both] Miniaturize!

- Hey, wait for us, buddy!

- Hang on!

- [Both] Whoa!

- [Chris] Bumpy, bumpy, bumpy, woah!

(screams) This is a zig-zaggy ride!

Wah!

Ahh!

- [Both] Whoa!

- That's life for a mongoose.

High energy, high speed and quick!

- [Both] Wah!

- [Chris] What if he never stops moving, how're we going to figure out his amazing power of venom immunity?

- Oh no, I think we're about to find out!

- [Both] Whoa!

- Mongoose, cobras, venom immunity?

What are they talking about?

- Immunity.

That means the snake venom is harmless to a mongoose.

How can that be?

- [Both] Whoa!

- [Chris] Hang on bro!

Ah!

- [Martin] Uh-oh.

It's a standoff.

The cobra's on defence.

- [Chris] And the mongoose on offense.

- [Both] Whoa!

- [Martin] It's venom-filled fangs and a sudden strike.

- [Chris] Versus quick agility and the speedy counterattack.

- People think cobras are always the aggressor, out to bite everybody.

But Hoodie's scared.

He's protecting himself from a serious predator.

- Exactly!

Martin, look out!

Whoa.

- [Both] Whoa!

- It's a hit!

Checking vital functions.

The messages are still flowing fine.

Uh-oh, but here comes the venom.

The venom molecules don't fit in the receptors.

They can't clog them.

So the messages can still get through.

And the heart keeps beating.

His venom immunity power is working!

- Amazing!

But he better not push his luck.

It's only partial immunity.

Too much venom can still be deadly.

- [Both] Whoa!

Ah!

Ah!

Woah!

Woah, woah!

- [Martin] Hoodie must be getting tired.

That's part of the mongoose plan.

Tire the snake.

- [Both] Ah!

Wah!

Wow!

- [Martin] That's it.

It's over.

- Aw, I feel so bad.

- Aw, yeah.

- The cobra just wanted to be left alone.

Just defending himself.

- Yeah, but we always got to remember one thing.

- [Martin] It's just how nature works.

Predators and prey.

- [Chris] Yup, no bad guys.

- No bad guys.

Well, let's grab my Creaturepod while we still have the chance.

- Mission Accomplished.

Let's get back to normal size.

- Got the Miniaturizer?

- I thought you had it!

- Uh-oh.

- It looks great, Aviva.

Hoodie would be proud.

- I hope so.

I made the pattern on the back of the hood exactly like his in his honor.

And the fang programming is complete too!

Ready to print discs.

Get ready for one cool reptile suit.

Jimmy, teleport!

- And zap it!

Wait for it and.

- [Both] Whoa!

- Oops!

Time to recalibrate my controller.

- [Both] Cobra Powers!

Thanks!

- You're welcome.

Cobra powers should help you get around a little better.

- [Both] Insert disc.

Touch cobra.

Activate Spectacled Cobra Power!

- Wow!

Check out the hood action!

- And fully functioning fangs!

- Wow!

Awesome!

Uh-oh.

Let's slither, bro!

- [Both] Gotta find that Miniaturizer!

- I think we'd better get out there and help them find it.

- Yeah, now we know, even the great defense of cobra powers has limitations.

- Back soon!

- Good luck!

- [Chris] Hey, with this cobra defense we're pretty much unstoppable out here.

- Yeah, nothing to worry about.

Uh, except maybe a mongoose or raptor.

- [Both] Wah!

- You've got to be kidding me!

- [Martin] Why is everybody lying around by our stuff today?

- I know!

Hey, do you think?

Nah.

- What?

- Well, do you think, with cobra power, we could get a tiger to move?

- Well, tigers do avoid cobras.

Because cobra venom is powerful enough to kill a tiger.

- [Chris] Exactly!

Even an elephant.

So go ahead.

Give it a try.

- Huh?

What?

Why me?

- Well, you lost your Creaturepod in the first place.

- I know, but, hey, two cobras are better than one, bro.

- Oh okay, cobra power to the Minaturizer rescue!

- [Both] Uh-oh.

- Defense posture!

- Activate hood!

- We've got to look as big and tough as possible.

- I'll show him the back of my hood.

See that Tiger?

Looks like two crazy giant eyes, right?

You don't want to mess with us.

- It's not working!

Engage Fangs!

A little mock strike.

- Ooh, he definitely knows about cobras.

- [Both] Yes!

No!

- That's even worse.

Ugh, how'd we get into this mess?

- [Martin] Well, uh, I might've lost my Creaturepod.

- [Aviva] Just look out for snakes.

- Believe me, I'm watching where I step.

- Oof.

- Oof.

Aviva, that's - a - King Cobra!

- Um, one minute your royal highness.

What?

A King Cobra?

- Yeah, while I was researching cobras, it turns out, the King Cobra is the biggest.

In fact, it's only the largest venomous snake on the planet!

- It must be over 16 feet long!

And a third of it's body is standing straight up looking us in the eye!

Ahem, your majesty.

We're just going to give you your space.

- [Koki] Whoa, it can even slither while standing up like that.

- Koki, let's just keep backing up slowly.

- [Koki] Whew!

That was close.

- [Aviva] Sure was.

- A nest.

The cobra has a nest!

- So it's not a King cobra.

It's a Queen cobra?

Well, at least it's a Queen King cobra.

You sure it's a nest?

- [Koki] Yeah, they're the only snake in the world that are known to build nests and they guard them too.

- Wow, this is one special snake.

(gasps) Don't move.

- What now?

- A King Cobra scale.

You know what this means?

- I got to stop bumping into snakes?

- I can make a King cobra upgrade to the Creature Power Suits!

Thanks Queenie!

But I wonder where the King King Cobra is?

(suspenseful music) - How do you get a tiger off a Miniaturizer?

- You wait.

- Chris, look!

A fellow cobra!

- Awesome!

A King Cobra!

- Hey check it out!

We're cobras too!

Come on over, Co-bro!

(laughs) Yeah, hey with cobra powers we've got nothing to worry about.

- What?

Whew.

- [Both] Whoa!

- Huh?

What was that all about!

- Uh, Martin, we forgot.

King Cobras are snake eaters!

And they love eating other cobras!

Slither!

- [Both] Ah!

Oof!

- Untie it!

- [Both] Ah!

- Don't I have to program a stronger venom into the King Cobra update of the power suit?

- Actually, the King Cobra's venom isn't as strong as other cobras.

- What?

But they hunt other cobras!

- I know and cobras have immunity to venom.

But like the mongoose, they're only partly immune.

So the way the King Cobra deals with it, is by making lots of venom.

They can pump huge amounts of venom into their predators or prey.

(hissing) So much venom, that even the other cobras can't deal with it.

- Wow, okay got it.

I need to modify the venom glands then.

- You know, with the male King Cobra out there, we should really find Chris and Martin.

- But this is so cool.

I'm sure they're fine.

- [Both] Where is he?

- Do you see him?

- No, but he doesn't have to see us.

He's got that tongue remember?

That tongue's used for smelling.

He'll be able to smell the ground and track us down!

- I know.

They can track prey over 300 feet away!

Something's there!

- [Both] Ah!

- [Chris] Slither!

- We got to deactivate, bro!

- We can't!

Not until we can get to normal size.

Being tiny is dangerous too!

- Oh yeah.

- [Both] Slither, bro!

Ah!

- Whoa!

Mongoose alert.

- Aw, it's not as easy being a cobra as I thought.

- [Both] Ah!

- Ah!

Oh, oh.

He's got me, bro!

But it's a good thing I have Cobra Powers right now!

Venom Immunity to the rescue.

- Yeah, but it won't last forever.

We've got to get him off!

Ah!

Oof!

- Um, Martin, what're you doing tangled in a tree?

- Long story.

Just get me down.

I got to get to Chris!

(whimpers) - [Chris] Oh no, the Immunity meter is rising.

The suit can't take this much venom!

- Oh no!

We got to help Chris.

Here, Martin, use this!

- King Cobra Power!

Oh, that'll even out this fight!

I'm comin', bro!

Activate King Cobra Power!!

Now it's King versus King!

Sorry, buddy.

Cobra Strike!

- Whew, thanks bro.

Just in time.

Immunity intact.

- Missed me!

- Uh-oh, King Cobras will even eat their own kind.

Okay, I've got a plan.

(groans) - Uh-oh, he's way bigger than me.

What do you say we call it a draw buddy?

I mean, hey, you're the real King.

I give, I give!

- Don't give up so fast, bro.

Two King Cobras.

- Are better than one!

- Way to go!

- That was cool!

- Yeah.

This suit is awesome!

- Hey, look who's up?

Finally we can get back to normal size.

- Great!

And then there's something you've just got to see!

- Wow, what a great find!

A real King Cobra nest.

- Queenie here, helped us learn how to make the Power Suit.

- Well, that's definitely Mission Accomplished.

We got your Creaturepod back from one of the most venomous snakes in the world.

- And got safely back to normal size.

But uh, bro, sorry that losing my Creaturepod almost got you eaten.

I'm definitely going to be more organized, starting now!

- I'll believe it when I see it.

- Oh yeah, watch!

Hm.

Uh, hm, hm, hm.

- This could take a while.

- [Chris] Yeah, fortunately we have a little time before those King Cobra eggs hatch.

Let's get an inside view of the nest.

- [Aviva] Looks like time's up, they're hatching!

- Oh!

I can't miss this!

- [Chris] The first hatchling.

Welcome to the world.

(chuckles) - I'll call her, Princess.

Princess, the baby King Cobra.

- [Aviva] Aw, they're so cute.

- Yeah, but don't be fooled.

Their venom, that double whammy Deadly Defense and Prey-disabling Offense is at full strength from birth.

- Uh-oh.

Then we'd better give these guys plenty of space.

- [All] And back off!

- Oh no no no no no no!

I'm out of here!

- Okay, well, guess I gotta organize later.

- [All] Mm-hm Jimmy!

- No doubt about it, cobras have some awesome creature powers, that amazing defensive hood, and a powerful venomous bite.

- Now let's compare the cobra and another famous venomous snake and see how they use their venom and try not to use their venom.

This is the Western Diamondback Rattlesnake.

Check out the diamond pattern going down her back.

This pattern helps it stay hidden from its predators like hawks, ro adrunners, and Spotted Skunks.

- Back in India with the King Cobra.

The King Cobra's black body helps to camouflage the snake from predators like Monitor lizards, eagles and mongoose.

But this posture is its main form of defense.

The snake rises up, spreads out that hood, and tries to make itself look as big as it possibly can.

That's the snake saying, "I'm big, I'm powerful and I have a poisonous venom.

Don't get any closer and leave me alone".

- The rattlesnake has a different feature for the same purpose.

If a predator makes the rattlesnake nervous or scared, she rattles the rattle.

She's saying, "I'm scared.

I have a defense, but I don't want to use it unless I have to".

So if you hear a rattlesnake rattling, always back off and give that snake its space.

- Most venomous snakes, like this King Cobra, don't really want to use their venom for defense.

They want to use it to catch prey.

King Cobras are active hunters which means they actively track and chase down their prey.

A bite from a cobra is powerful enough to kill 20 humans or an elephant.

All right bud, I'm out of here.

So remember, venomous snakes will use their venom to defend themselves if they feel threatened and that can be dangerous to people.

- Never approach a venomous snake.

Always remember to give a snake its space and lots and lots of it.

- Keep on creature adventuring.

- We'll see you on the creature trail!
