Hey, it'’’s the Kratt brothers here.

I'’’m Chris.

I'’’m Martin.

And it'’’s alligator feeding time.

(Laughing) We'’’ll start with the smallest and move up from there.

CHRIS: This 1-year-old alligator will eat anything he can catch and fit in his mouth.

And here'’’s a favorite first food of an alligator hatchling, dragonflies.

Hungry?

Who knew dragonflies were so good?

This is a 3-year-old alligator.

She'’’s definitely ready for fish and mammals and much bigger food.

You got something, Chris?

Easy, easy, girl.

There you go.

How about that?

(Laughing) Wow.

And the biggest alligator gets the biggest fish.

Ooh.

Whoa, fish juice in the face!

Right down the hatch!

An alligator this size has a bite force of about 1,000 lb.

MARTIN: The biggest crocodiles and alligators have a bite force of 5,000 lb.

That is the same amount of pressure as a pickup truck sitting on top of you!

That'’’s the power of this reptile'’’s jaws.

But alligators and crocodiles are about more than just sharp teeth and a deadly snap.

Imagine meeting a completely different side to a crocodile, a side that is dedicated, protective and maybe even caring!

Then we'’’d be able to appreciate what these creatures are really all about.

What if?

MARTIN: As long as she doesn'’’t see us, we should be okay.

There she is.

(Growling) Whoa, the mighty Nile crocodile of Africa!

At over 20'’’, one of the two largest types of crocodile in the world.

(Growling) She'’’s picked a spot.

It shouldn'’’t be long now!

CHRIS: Oh, yeah, digging is step one.

Operation Crocodile Nest is underway.

Aviva, are they ready yet?

AVIVA: Almost.

But, guys, I told you this plan of yours is not going to change my mind.

I just don'’’t like crocs, period.

Oh, you'’’ll like them after this adventure.

Yeah, Operation Crocodile Nest will prove that there'’’s more to crocs than you think.

They'’’re just big, creepy reptiles.

All I'’’ve seen them do is try to bite things.

They give me the shivers.

Yeah, that'’’s why they'’’re cool.

(Screaming) When they'’’re far away from me.

Exactly!

See, and you guys think that when I see her lay eggs, it will make me like the big meanies all of a sudden?

I don'’’t think so.

Miniaturizer ready!

Let'’’s do this.

Miniaturized and standing by.

Okay, it'’’s done.

(Screaming) (Gasping) Delivering secret disguise now.

Okay.

Go, go, go, go, go!

(Panting) Oh.

Whoa!

Huh?

Look at those huge scoopfuls of sand she grabs with her hind feet.

We better hustle, Chris!

CHRIS: Whoa, now, this an impressive face.

I'’’ll call her Crocodilla.

MARTIN: Oh, check out those teeth!

64 dagger teeth!

Twice as many as we have.

Oh, it'’’s a good thing we just look like a couple of crocodile eggs.

See, you don'’’t trust her either.

Just don'’’t awaken the beast, guys.

Ugh.

MARTIN: I don'’’t even think she sees us.

She'’’s in that special trance that crocodiles get into when they-- Lay... their... eggs.

The trance.

She'’’s in step two, egg laying.

Let'’’s go!

What?

I'’’d I crack?

No, you'’’re good.

56, 57.

57 eggs!

Ooh!

One by one, she lays her eggs in the nest chamber.

Whoo, if all these hatch, there will be lots of little Nile crocodiles running around here in about three months.

BOTH: Whoa!

She'’’s burying them!

Are you kidding me?

She just drops her eggs in a hole and covers them up?

I told you guys, that is one cold creature.

CHRIS: We'’’ll see.

Let'’’s get in there, Martin.

What?

Get in where?

Where else?

The nest.

We'’’re crocodile eggs!

Those are our pals down there, Aviva.

Besides, how else are we going to find out the secrets of crocodile birth?

Let'’’s get cracking, Martin!

BOTH: Woohoo!

Guys, wait!

We'’’re losing you!

I'’’ll have to make some adjustments to the signal receiver.

Whoa, she'’’s stomping the sand.

Looks like she'’’s packing them in.

I knew this was a bad idea.

Never trust a crocodile.

I'’’m getting a signal again.

Yo there, guys, we'’’re fine!

The eggs have landed!

She'’’s done.

We did it!

(Laughing) We'’’re in the crocodile nest!

Woohoo!

Now what?

CHRIS: Oh, she'’’s holding her mouth open.

It'’’s getting pretty hot up there.

About 90° today.

But cooler down here.

CHRIS: Yeah, this sand is amazing.

Down here under a layer of sand, the temperature hardly changes at all.

It'’’s been about 85° day and night, the perfect temperature for these eggs to develop.

Oh, your mama knew exactly what she was doing when she put you in here, Chomp I thought that one was Crunch?

No, that'’’s Jaws.

This is Chomp, that'’’s Munch, Snapper and Fred!

CHRIS: She'’’s gone.

Crocodilla'’’s gone!

Where'’’d she go?

Uh-oh, that'’’s not her.

(Beeping) Oh.

Guys, don'’’t look now, but it'’’s a raid!

Too late.

I'’’m already looking!

Whoa!

Oh, no, monitor lizard attack!

She sniffed out the nest!

Oh, no, she'’’s hungry for eggs, and we'’’re all gonna get munched!

Oh, no!

These monitors are one of the major predators of crocodile eggs.

No, wait.

That'’’s Fred!

Stop!

BOTH: Egg thief!

I can'’’t believe that mother croc just abandoned her eggs.

She should be protecting them.

Uh-oh, I think the lizard'’’s gonna regret this.

Look!

Incoming croc!

(Grunting) Now, that'’’s a protective mama croc.

(Growling) (Growling) Woo, nice rescue, Crocodilla!

Got to get Fred.

(Grunting) Hurry, Martin.

She'’’s covering the nest back up.

I hope she doesn'’’t see me and think I'’’m taking her eggs.

Don'’’t worry.

I'’’ve got it covered.

Nothing to see, girl.

One crocodile egg, over easy.

Come on, Chris!

Hey, but this is cool.

I'’’ve never ridden a crocodile before.

I'’’ll stay out here with Crocodilla, find out more what being a mama croc is all about.

Okay, keep that creature pod on!

You got it, bro.

Look out for those lizards.

KOKI: Huh, who would have guessed crocodiles were such protective moms?

Huh, or she was just hungry for a lizard lunch.

No, it says here that lots of predators try to get croc eggs: monitor zards, honey badgers, and even baboons.

Wow, I thought crocodiles picked on everyone else.

But I guess they get picked on sometimes too.

Only about half of her eggs usually survive the predators.

So she guards her nest day in and day out for months while the eggs develop.

Want to go riding today?

Ah, that'’’s what I thought.

Raining hard out there.

What'’’s up with the croc?

Guess.

Amazing, she doesn'’’t even eat for months!

Whoa, months?

Chris and Martin must be starving!

P.B.

and J. coming at you, guys!

Hm.

Whoa!

Thanks, Jimmy.

Oof!

Aw, thanks, Jimmy.

I got to admit, she does seem pretty dedicated.

Uh, guys, she'’’s gone.

What?

Where did she go?

Woohoo!

Now this is the way to cruise an African river, croc-back riding.

What about the eggs?

Huh, I knew this dedication thing was too good to be true.

Aw, it'’’s a super-hot day.

Crocs are cold-blooded, remember?

Their bodies take on whatever temperature is around them.

So when they get too hot, a croc has no choice but to cool off in the water to survive.

Well, she'’’d better get back to those eggs fast.

She is.

Uh-oh, we just have to get past those hippos.

What do you mean, get past them?

Now, that'’’s a cute animal, my kind of creature.

(Bellowing) Whoa, crocodiles and hippos both rule these rivers.

And hippos are just as tough.

(Bellowing) Those jaws can bite a 12-foot crocodile in half.

(Grunting) Let'’’s get out of here, Crocodilla!

(Inhaling) Whoa!

Woohoo!

Nice move, Mom.

Way to dodge those toughies.

Aviva, what are you doing?

Hippos are amazing and able to stand up to crocs like that.

I know just the invention we need to keep those crocs in line.

No fair.

You'’’re favoring the hippos.

The croc mom was just minding her own business.

The hippos went after her.

She'’’s just not a fan of these crocs.

MARTIN: Hey, Fred, all curled up and cozy in there.

Looking good, little guy.

Oh, wait a second.

You'’’re not a guy.

Fred'’’s a girl!

Koki, come in!

Go, Martin!

What'’’s the temperature of this nest been?

85°, same as almost everyday you'’’ve been in there.

Oh, that'’’s it.

What'’’s it?

Their temperature!

That'’’s why all the baby crocs are girls!

Because of the temperature?

Yeah, crocs become girls or boys based on how hot or cold the eggs are.

If the nest is 88° to 93°, they grow into boys.

If it'’’s colder or warmer than that, they grow into girls.

That'’’s weird.

Cool, but weird.

Oh, I got to rename everybody!

Okay, let'’’s see.

Crunchina, Chompella, Munchette, Snapifer and Frederica.

Oof!

Oh, no!

Nest to mama croc!

Come in, mama croc!

We'’’ve got another egg thief!

We'’’re on our way, Martin.

Had a hippo delay.

Hang tight!

Uh-oh, hurry, Mama.

Oh!

Huh?

More eggs?

(Gasping) A soft-shelled turtle.

What are you doing laying your eggs right by a crocodile nest?

You know Crocodilla doesn'’’t like anybody messing with her eggs.

(Gasping) That'’’s it!

This turtle knows that if she can secretly get her eggs close to a crocodile nest, they'’’ll be guarded by the mama croc too!

It'’’s brilliant!

Chris!

Chris, call it off!

False alarm!

It'’’s a turtle!

Turtle?

Uh-oh, crocs will eat anybody they find messing with their nests.

Whoa, Crocodilla!

Slow down, girl!

Hurry up!

She'’’s coming!

How do you speed up a turtle?

How do you slow down a giant croc?

Whoa!

Whoa, take your time!

Relax!

Yikes!

Okay, see you later.

Thanks for stopping by.

Go, go, go!

Whoa!

(Hissing) Ugh!

Whoo!

That was a close one.

Yeah, you can'’’t hold back a mom on a mission.

Come on, Aviva, there is a softer side to these crocs.

Well, I am pretty impressed with how protective croc moms are.

Even the turtle mom knows it.

But crocs still always seem to be snapping their jaws at everybody.

But the hippo snapped at her.

And the monitor lizard tried to eat her eggs.

Still, I'’’d like them more if there was a little less jaw snapping.

(Beeping) MARTIN: Hatching!

We'’’ve got a hatcher here.

Which one is it?

It'’’s little Frederica.

She'’’s busting through!

She did it!

Welcome to the world, little croc!

Yeah!

(Chirping) She'’’s making a baby croc call.

And her sisters are calling too.

Baby crocs time their hatching so that they all do it together.

MARTIN: Yeah, there'’’s Jawsana, Crunchina, Chompella, Munchette.

Oh, come on, Snapifer, you'’’re doing great.

Even the little soft-shelled turtles are hatching.

It'’’s a hatch fest.

Yeah, just one problem.

It'’’s getting crowded in here.

That'’’s because we'’’re buried under a whole bunch of sand.

Uh-oh.

Help!

Oh, no, the baby crocs are all hatching but now they'’’re trapped in their own nest.

(Chirping) I can'’’t believe I'’’m saying this, but those baby crocs are kind of cute.

But what'’’s that sound they'’’re making?

That'’’s it!

The baby crocs are calling for their mom.

We got to make more noise.

Louder, everybody!

(Imitating babies) KOKI: Aviva, check it out, topside!

She hears them!

Guys, she hears you!

I can'’’t believe it!

She'’’s coming to the rescue!

Maybe I was wrong about her.

All right, nice croaking, gang.

Hey, Chompella, don'’’t stop now.

Here'’’s Mama.

Whoa, I never thought I'’’d be so happy to see that face.

Uh, on second thought-- She'’’s eating her babies?

I told you!

Oh, these crocodiles!

Just when I was starting to trust them!

CHRIS: It'’’s fine!

She'’’s not eating them.

She'’’s just picking them up.

She knows how sharp her teeth are so she'’’s super-careful.

Huh?

Martin?

It'’’s comfy in here too.

Her throat pouch holds 20 of us.

She'’’s even taking the baby turtles.

That'’’s nice of her.

Okay, I think we got a full load.

Bus is packed and ready to go.

But where are you guys going?

To the water!

Full croc ahead!

I can'’’t believe it!

Now I'’’m totally blown away.

Croc moms are-- Are-- We know.

They freak you out.

No, they'’’re the coolest!

What kind of mom is more dedicated, more committed?

They'’’re amazing!

Okay, first and only stop: the crêche.

That'’’s a fancy word for the nursery pool, a nice calm, quiet section of the river.

Everybody out.

Whoa, hey, everybody'’’s looking good.

You know, baby crocs are expert swimmers from the minute they'’’re born.

And mama'’’s off to get the rest of the kid crocs.

We'’’ll keep an eye on these ones for you!

Uh, Jimmy, can you pass me those rivets?

What are you working on, anyway?

Oh, it'’’s a-- KOKI: Oh, no, we'’’ve got a problem.

What?

That!

Guys, behind you.

Look who'’’s back!

Uh-oh, these monitor lizards don'’’t only like eggs.

They think baby crocs are pretty tasty too.

You'’’ve got to fill in for Crocodilla.

Be a mother croc and get those meanies.

Aviva, I thought you thought crocs were the meanies.

Are you kidding me?

She'’’s just protecting her babies.

Crocs are great.

Now help them, quick!

We can'’’t fill in for a mama croc!

We don'’’t have a crocodile disc for our Creature Power suits.

Unless this will work.

Aviva made a disc with gharial croc power when we were adventuring in Asia, remember?

Since they'’’re both crocodilians, it just might work.

Activate Creature Power suit!

Whoa!

Come on!

Come on!

Yes, it worked!

Sorry, a couple more mama crocs just showed up.

To the baby crocodile rescue!

(Gasping) Back off, Marabou Stork!

These croc kids are under our watch!

(Gasping) (Hissing) Easy, honey badger.

No baby crocs for lunch today.

(Growling) Woo, nice croc action, bro.

You too, but I hope Crocodilla gets back soon.

There'’’s a lot of predators out here.

Okay, better do a quick head count.

Let'’’s see, Crunchina, Chompella, Munchette, Snapifer.

Hang on there, Jawsana.

Wait, where'’’s Frederica?

Oh, there you are.

Well, everybody'’’s safe and accounted for.

Uh-oh, the transformation'’’s not holding up.

Chris, here comes Crocodilla with the last load of baby crocs.

(Growling) Uh-oh, what'’’s Crocodilla going to think if she finds a couple of Wild Kratts with her babies?

Whoa, I'’’m pretty sure she'’’s not happy to see us!

Reactivate Creature Power Suits!

Uh, it'’’s just a misunderstanding.

We were protecting them while you were getting the others.

Yikes.

MARTIN: A hippo sub?

Aviva!

Get in guys, quick!

Ugh!

You'’’re the best, Crocodilla.

After all, Nile crocs just might be the greatest moms in the world, a crocodile of a mom.

CHRIS: Woo, mission accomplished.

We got a true insider'’’s look at a totally different side of the crocodile.

And I'’’ll admit it: I love crocodiles now.

I shouldn'’’t have judged them before I got to know them.

They'’’re so much more than the mean, scary brutes I thought they were.

I can'’’t believe that they'’’re so caring and protective of their babies.

Yeah, the softer side of crocs.

Where'’’s Martin?

Well, Mom still protects the baby crocs, but they need to catch their own food from day one.

So I thought we'’’d help them practice.

Okay, if you want to grow big and strong like Mom, you need to start small.

Minnows, water bugs, dragonflies.

Okay, who'’’s first?

Come on, take your best shot.

Whoa, that'’’s it, Frederica!

(Laughing) Nice snap!

And a good dodge, Martin.

Whoa!

Nice try, Chompella.

You almost had me.

Way to make your mom proud.

Woo!

(Laughing) Whoa!

(Laughing) So there'’’s a lot more to crocodiles and alligators than most people think.

Who would have thought she'’’d be such a devoted and protective mom?

(Chirping) And baby alligators really depend on those moms.

(Chirping) Do you hear that sound?

That'’’s her calling for her mom.

When she'’’s born inside the nest, she makes that call and also when she'’’s out on her own and she needs the protection of her mother.

We better bring her back to her mom.

It'’’s not just crocs and alligators.

A lot of reptiles put a lot of time and energy into protecting their eggs.

Like ball pythons.

This ball python is an incredible mother.

She sits by her eggs, protecting them and controlling the temperature and humidity, not eating for 90 days.

If the eggs get too cold, the ball python mother will shiver her muscles to warm them up.

Come on, we got to show you something.

These are ball python eggs.

And in order to hatch them, we have to keep them in a constant temperature and humidity just like their mom does.

CHRIS: To do that we'’’ll use this machine, an incubator.

And just close it up, slide them in, and wait till they hatch.

It'’’s time!

They'’’re hatching!

Each snake pokes his head out of the egg, has a look around, and then goes back inside.

They'’’ll keep doing this for a couple of days.

CHRIS: Until finally, two days later, the baby pythons are ready to slither out of the eggs for good.

MARTIN: They'’’re pretty long when they'’’re born and look like miniature versions of their moms.

Unlike the little crocs who are protected by their mom for up to a year after they hatch, the little pythons are on their own from the moment they slide out of that egg.

And even at this small size, they'’’re ready to go out and hunt mice, birds and other small animals.

BOTH: Happy birthday, baby pythons.

Keep on creature adventuring.

And discovering there'’’s more to some creatures than you might think.

See you on the creature trail.
