♪ Wild Kratts ♪ Hey, I'’’m Chris.

And I'’’m Martin.

Together, we'’’re the Kratt Brothers.

But tonight we'’’re the Bat Brothers.

Because we'’’re out looking for bats.

Maybe we can find one sleeping in its day roost.

Chris, how about this?

An abandoned mine.

Whoa.

MARTIN: Come on.

Let'’’s gear up for a bat cave expedition.

Oh, yeah.

Never enter a cave or abandoned mine unless you have years of caving experience.

Whoa!

What an awesome cave.

(Bats squeaking) Shh, Chris.

Listen.

Squeaking.

Ah, little brown bats.

CHRIS: Oh, this bat'’’s starting to wake up.

You can tell because he'’’s doing the wake-up shiver where he gets his muscles going, warms up his body and then he'’’ll fly.

Little brown bats are so tiny.

They'’’re less than half the size of a mouse.

Where are you going, buddy?

Getting ready to fly?

There he goes.

CHRIS: Oh, imagine if we could hang out with these little brown bats wherever they go and do whatever they do.

Imagine if we could fly like bats and had all their awesome bat powers.

What if?

What if?

Yeah!

These Buzz Bikes are the best for creature adventuring.

Yeah, we flew right by a peregrine falcon.

And we saw that cute, fuzzy family of raccoons and kept up with a coyote.

Yeah, but we lost the Tortuga.

Which way is home?

Oh, that'’’s easy.

Yeah, no problem.

It'’’s that way.

It'’’s that way.

Just give me a sec.

Accessing Buzz Bike homing map.

Hurry up, Koki.

Jimmy'’’s baking his famous brownies and I'’’m hungry.

(Insects buzzing) Are you almost done, Koki?

I'’’m not the only one who'’’s hungry.

The mosquitoes are too.

Oh, yeah.

Just like clockwork.

As soon as it gets dark, out come the little bloodsuckers.

Okay, got it.

Tortuga is that way.

And not a second too soon.

Let'’’s head back.

Buzz Bikes away!

(Laughing) What was that?

Are you okay, Koki?

Yeah.

I thought I saw something creepy, but I guess it was just my imagination.

Let'’’s head back to the Tortuga.

Hm?

That'’’s better.

Brownies are ready!

Ah.

Jimmy, where are the brownies?

Yo, crewbies, brownies are served.

Mm, delicioso.

(Squeaking) Mm.

Mm, I want this one.

(Chomping) Jimmy, your brownies rule!

My Grandma Jimmina'’’s recipe.

Hey, Martin, aren'’’t you going to have one?

Oh, stop me at 10.

Yummy.

(Gasping) Guys, come on.

Chew with your mouths closed.

Uh, bro?

There'’’s a bat in the brownies.

What?

Cool.

(Laughing) A bite-sized little brown bat.

And that'’’s what I'’’m going to call you: Bite-Size.

KOKI: Am I in a nightmare?

You'’’re holding a blood-drinking, rabies-infected, vicious little monster.

CHRIS: What?

Not true.

Who told you that about bats?

My Grandma Jimmina told me.

Well, Jimmy, your grandma sure knows a lot about great brownie recipes, but she knows nothing about little brown bats.

Or any other kind of bats.

There are about 1,100 species of bat in the world.

About 720 are insectivores, meaning they eat bugs and moths.

CHRIS: Like the bent-wing bats that go high into the sky eating millions of moths each night.

MARTIN: Another kind of bat are fruit bats.

They'’’re also called flying foxes.

And they eat fruit.

Some, like the ghost bat, eat frogs, birds and other bats.

CHRIS: Only one drinks blood: the vampire bat.

And usually from sheep and cows.

Yeah.

They really are harmless and helpful fellow mammals.

Plus wings.

Well, I guess it'’’s not attacking anybody.

(Squeaking) (Screaming) JIMMY: Bat attack!

Bat attack!

Yes, it is!

Yes, it is!

(Shouting in Spanish) Ah!

Bat attack!

Bat attack!

(Mosquito buzzing) Well, you were kind of right, Jimmy.

It was a bat attack.

But the bat wasn'’’t attacking you.

It was attacking something else.

Something you want it to attack.

Where?

Who?

What'’’d I miss?

I don'’’t get it.

Check out your arms, Jimmy.

What?

My mosquito bites?

AVIVA AND KOKI: Mosquitoes?

They'’’ve been attacking us for days.

(Buzzing) CHRIS: Now check out Bite-Size in full bat attack!

(Gasping) JIMMY: So that means that when the bat was flying around my head, he wasn'’’t trying to suck my blood?

He was trying to catch a bug that was trying to suck your blood.

Oh!

You'’’re right, MK.

Bats are helpful.

(Koki grunting) (Mosquitoes whining) CHRIS: Six.

Seven.

Eight.

Nine.

Ten!

Ha!

This little brown bat caught 10 mosquitoes in a minute.

That means this little brown bat can catch... (Mouthing) 600 mosquitoes in just 1 hour.

That means... (Mouthing) that in 2 hours, 833 little brown bats can catch 1 million mosquitoes.

Oh, bats make the world a less itchy place.

Goodbye, bug spray.

Hello, bats.

AVIVA: Okay, that does it.

Any creature that is so good at catching mosquitoes is a friend of mine.

Hola, little Bite-Size.

You are so delicious.

His rear claws are like hooks so he can hang upside down and rest.

Hanging hook claws.

What a cool feature.

If you like that then check this out.

A bat wing is made of long, thin fingers with skin stretched between them.

So a bat wing is really a big, flying hand.

Ha!

I'’’m making a Bat Creature Power Suit.

Got to go.

How come bats are so good at catching mosquitoes?

And how can bats catch mosquitoes in the dark?

Because they have an awesome power: echolocation.

First a bat gives off a little squeak.

I don'’’t hear anything.

That'’’s because the squeak of a little brown bat is too high-pitched to be heard by human ears.

But with the animal amplifier... (Bat squeaking) He'’’s making high, squeaky sounds.

Yeah, about 20 squeaks per second.

the sound travels through the air in waves.

And when it hits a mosquito, a tiny wave of sound bounces back and travels to the bat'’’s big ears.

That'’’s why bats have big ears: to hear those tiny sounds.

And the bat keeps squeaking and squeaking and hearing the tiny pieces of squeak.

And in his brain, he gets a picture of where the mosquito is.

And he follows him.

No matter how dark it is or what loops the mosquito makes.

He can follow him, tracking him down until... crunch time.

It'’’s like a video game in fuzzy 3-D.

Bats are completely cool.

And I can make the best game out of this.

Call it "Bat Attack."

Yeah.

You get to be a bat and have to eat millions of bloodthirsty mosquitoes that are trying to take over the world.

KOKI: Who cares?

All I want to do is get my zucchini plants growing so you can make that yummy chocolate zucchini bread of yours.

AVIVA: I love bats.

(Giggling) All right!

Two bat fans down.

One to go.

Forget it.

There is no way you will ever talk me into liking bats.

(Screaming) Hm!

AVIVA: Perfect timing, Bite-Size.

The Creature Power Suits and the bat power discs are ready to go.

I can hardly wait to see the guys try them out.

CHRIS: Me neither.

MARTIN: With you there, bro.

Here you go.

Thanks, Aviva.

Oh, yeah.

This is going to be great.

Don'’’t thank me.

Thank Bite-Size.

He showed me just how amazing and resourceful little brown bats really are.

If it weren'’’t for him, I might still think bats are just little, creepy animals.

Well, bro?

Let'’’s do this.

Let'’’s do this.

Activate Creature Powers.

Hey, we'’’re the Bat Brothers now.

And we'’’re flying to the creature rescue.

We are?

What creature rescue?

Don'’’t know, but there'’’s always a creature rescue.

(Both laughing) I think you two should take a trip through the Miniaturizer.

Not enough room in here for those bat wings.

Besides, little Bite-Size brownie boy or whatever you'’’ve called him this time is waving bye-bye now.

CHRIS AND MARTIN: No!

Bite-Size!

Come back!

Hurry, Aviva, before we lose him.

Miniaturizers powered up.

We'’’re good to go.

Mm-hm.

CHRIS: Hey, Bite-Size, wait up!

Goodbye, and don'’’t come back anytime soon.

AVIVA: Come on, Koki.

I used to think bats were icky creepy.

But now that I'’’ve got to know them, I like them.

Yeah.

Bats are cool.

What would be cool is my zucchini plants growing better.

It'’’s summer, and what'’’s summer without chocolate zucchini bread?

JIMMY: Yeah.

MARTIN: There he goes.

CHRIS: Follow that bat.

While the kids are snoozing, the bats are cruising.

(Both laughing) MARTIN: Oh, yeah.

CHRIS: Whoo!

MARTIN: I love Bat Power!

CHRIS: Good one.

Hey, did you notice something about Bite-Size, Martin?

MARTIN: He'’’s not catching mosquitoes anymore.

Hey, he must be full.

Because if insects are abundant, a little brown bat can fill his belly in the first 2 hours after the sun goes down.

Right you are, bro.

A brown bat can eat as many as 3,000 mosquitoes each night.

And almost all that happens right after the sun goes down.

Hm, speaking of going down, Bite-Size is heading straight for that pond.

He'’’s drinking on the fly.

Got to try it.

Got to try it.

(Gurgling) Not that thirsty.

(Groaning) (Chris laughing) CHRIS: It'’’s more like this, bro.

Little sips.

Like that.

Whoa!

Whoo-hoo!

(Chuckling) Uh, you were saying, bro?

Whew!

Bite-Size is a perfect name.

It'’’s a dangerous world out here for little brown bats.

Hm.

Maybe we should watch our backs with a little echolocation look-around.

Good idea.

I'’’ll give it a try.

(Squeaking) Something'’’s bouncing back.

Rhododendron bush down low.

Awesome!

My turn.

(Inhaling) (Squeaking) (Groaning) Oops.

Sorry, dude.

Let me try that this way.

(Squeaking) It'’’s working!

There'’’s a tree trunk and a branch and-- (Gasping) An owl!

A screech owl!

Fly, fly, fly, fly!

(Screaming) Ooh.

Follow Bite-Size.

(Screaming) (Panting and moaning) Another close one.

Tell me about it.

Hey, what'’’s this?

A bat roost.

Hm, so the little brown bats go out as soon as it'’’s dark, they fill their bellies and return to the safety of their roost as quickly as they can.

MARTIN: Hurry up, Chris.

I want to see!

(Grunting) Cool.

CHRIS: Hey, Martin.

Over here.

Next to Bite-Size.

MARTIN: Ooh, it sure is cozy in here.

And warm and dry.

And safe.

(Yawning) I could go for a bat nap.

Good one, Martin.

(Snoring) Hm.

Martin?

Boy, does my brother fall asleep fast.

A bat nap.

Yeah.

A bat nap.

(Yawning) (Chris snoring) AVIVA: Uh, Koki?

Don'’’t you think you should check in on the Kratt Bros?

KOKI: Oh, you mean the Bat Brothers?

No.

I'’’ve seen enough bats for one day.

One lifetime.

They freak me out.

I know, but why don'’’t we just check in on them real quick.

No watching bats?

Mm-hm.

All right, then.

Tortuga to Wild Kratts.

Come in, Wild Kratts.

Told you bats were trouble.

Wait a sec.

There'’’s a thunderstorm.

Modifying fly cam transponder for storm interference.

(Thunder crashing) Huh?

What?

How long have we been asleep?

Sounds like a storm is passing over.

Directly over.

Uh, if this tree'’’s tall out in the open, I hope it doesn'’’t get hit by-- (Thunder crashing) Oh, no.

The storm knocked out our signal.

I'’’ll try to re-establish the connection.

(All gasping) Oh, no.

The bats'’’ home.

It'’’s completely destroyed.

Chris, Martin, are you guys okay?

(Chris and Martin panting) Yeah, we'’’re okay.

But Bite-Size and the rest of the bats are really shaken up.

CHRIS: And their shelter, their protection, their home has been totally destroyed.

KOKI: Poor little things.

Why was I so mean to them?

They'’’re just cute little fuzz balls who need a home.

Oh, no.

Where are they going to go?

Don'’’t look now, Chris, but I think we got another problem.

The sun is rising.

If you thought that owl was scary, it'’’s almost morning.

In the daytime, bats are much more vulnerable to falcons, cats, crows, foxes.

Bite-Size and his buddies are going to get devoured unless they find a place to hide.

But good roost sites are special.

They have to be just right for the bats.

With a small entrance chamber and certain specifications.

(Gasping) Bat box.

Bat box.

Nice one, dude.

If we build a bat box for them to hide in, that would-- Oh, no.

Too late.

They'’’re already taking off.

And in different directions.

MARTIN: Oh, no.

You know what'’’s in all directions?

Uh, no.

What?

Wild Kratts kids.

Of course.

They'’’re everywhere.

Good one, bro.

Jimmy.

Hm?

In my back pack.

Center pocket, left side in the mesh zip I have instructions on how to make a bat box.

Got it.

Time for me to help out some helpful and harmless little bats.

I'’’ve got a much better attitude now.

Make that a much better "battitude."

Input the geographical range of little brown bats with Wild Kratts kid addresses.

Wow.

They are practically everywhere in North America.

Wild Kratts emergency.

All Wild Kratts kids, especially at longitude 45 degrees north and latitude 75 degrees west.

Code creature rescue.

Build bat boxes and hang them outside immediately.

A bat rescue?

In our neighborhood?

Yeah!

When our bat box is done, they can live here.

Okay, we'’’d better keep an eye on Bite-Size and his bat buddies until the bat boxes are ready.

(Gasping) Peregrine falcon!

She spotted the bats!

We have to help them.

To the creature rescue.

To the creature rescue.

I'’’ll distract the peregrine falcon.

You stay with the bats.

Got it.

Hey, falcon.

Over here.

Catch me if you can.

Uh-oh.

He probably can.

(Screaming) But not this time.

Whoo-hoo!

Don'’’t worry, Bite-Size.

We'’’re not going to let any hungry predators eat you for breakfast.

(Raccoon chirping) (Gasping) A raccoon.

He can grab them right out of the air.

I'’’ve got to get there first.

Hey, raccoon.

Looking for bat snack?

Well, breakfast is served.

Come and get it.

(Grunting and gasping) That'’’s it.

Eyes on me just a little bit longer.

Sorry, raccoon.

Little brown bats are off the menu.

And me too.

♪ AVIVA: These kids are incredibly cool.

KOKI: They love animals.

Including bats.

Oh, wow!

Cool.

Yay!

Cool.

(Both laughing) (All laughing) Yay!

It'’’s working.

Kids in the target zone and kids from all over North America are reporting bats are moving into the bat boxes.

Yay!

But what about mine?

Which I'’’m going to put up for a special little bat who might want to live right close to a real bat lover with a super "battitude."

Hey, guys, you'’’re not going to believe this.

JIMMY: What?

You know where Bite-Size is headed?

AVIVA: Where?

CHRIS: The Tortuga!

Welcome to your new home, Bite-Size.

And I want you to know I really, really, really like you now.

And you know what else, Koki?

You put your zucchini plants in the right spot.

Because every time Bite-Size goes to the bathroom, it'’’ll drop into your soil.

And bat guano is the best fertilizer in the world.

KOKI: Wow.

Because of bats, it'’’s going to be a great year for zucchini.

And less mosquito bites.

And for discovering even more secrets about bats.

And for awesome creature powers.

And incredible creature rescues.

I'’’ve always loved hanging with bats.

(Chris laughing) CHRIS: Now that'’’s a great "battitude."

MARTIN: Little brown bats are so great.

They hang upside down throughout the day, sleeping.

I know what you'’’re thinking.

How can they hang there when they'’’re sound asleep?

Because a bat has claws that hook backwards.

So all the little brown bat has to do is hook his claws into a crevice and hang.

Sound asleep.

And check out these wings.

A bat wing is skin stretched out between long, skinny fingers.

Yeah, and those wings, they give this little brown bat the power to fly through the night and catch bugs right out of the air.

CHRIS: You can see his tail right there.

And the skin stretching between the hind leg and the tail forms a net that he can use to scoop up insects.

But there'’’s one problem.

Healthy little brown bats like this guy are becoming more and more rare because they'’’re being attacked by a fungus which causes a disease called white nose syndrome.

White nose syndrome is spreading so fast that little brown bats like this guy are in serious trouble.

They could become endangered.

We have to do everything we can to help them.

You thinking what I'’’m thinking, bro?

Oh, yeah.

Let'’’s gather up some Wild Kratts kids.

Who wants to build a bat house?

ALL: We do!

All right, come on.

This is going to be great!

A little brown bat can eat 300 mosquitoes a night.

So they'’’re really good friends to humans.

And in our bat boxes, they can put their back feet and hang.

Just like the way they do in the cave.

CHRIS: You guys are helping creatures.

MARTIN: Excellent.

Who wants to put the next nail in?

GIRL: I will.

CHRIS: You'’’re doing great.

They'’’re going to love it, aren'’’t they?

MARTIN: We are done!

We got a bat box!

Now we just have to find a place to hang it.

It has to be near the woods, it has to be near the water and it needs to be about 10 feet off the ground and facing towards the sun.

So let'’’s go find a place.

CHRIS: Let'’’s find a good spot for these guys.

There.

Good job!

It'’’s a great house for bats to live in.

They'’’re safe in here, and it keeps them warm during the day when they sleep or throughout the entire winter when they hibernate.

MARTIN: You can build bat houses too and help our friends, the bats.

Keep on creature adventuring.

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