MARTIN: Hey, we'’’re here in North America, near the Arctic Circle, in the middle of winter.

CHRIS: In a habitat known as the boreal forest.

MARTIN: With a herd of white-tailed deer.

It'’’s us, the Kratt Brothers.

I'’’m Martin.

I'’’m Chris.

And we'’’ve got a creature question for you.

A quiz of your knowledge of creature headgear.

CHRIS: Which is a tusk?

MARTIN: Which is a horn?

CHRIS: And which is an antler?

BOTH: Yeah!

And here'’’s a caribou, with antlers.

I really like your antlers.

Caribou have cool antlers.

CHRIS: Oh, yeah.

Antlers are a set of creature headgear that grows in every year, and then falls off.

Each year, the set of antlers grows in bigger.

Antlers grow on all members of the deer family.

Like white-tailed deer, elk, and moose.

Now, horns don'’’t fall off.

Horns are permanent.

They stay attached and they keep growing a little more every year, and keep getting bigger and bigger.

Musk oxen have horns growing out of the top of their heads.

And so do bison.

And big-horned sheep.

And tusks don'’’t grow out of the top of the head.

Tusks are teeth, and they grow out of the mouth.

And tusks just keep on growing and growing.

Elephants, walrus, and warthogs all have tusks.

Imagine if we could have one of these creature headgear.

Imagine if we could have the power of tusks, horns or antlers.

BOTH: What if?

You ready?

CHRIS: Oh, yeah, I'’’m ready.

Come on, Marty Moose, let'’’s see what you'’’ve got.

You can see.

Two palmated 20-point antlers that are going to scoop you up and flip you over.

Ha, unlikely.

Yeah?

What'’’s your play, bison brother?

Two unbreakable horns backed up by bison brawn.

Ha!

Antlers are more awesome.

Horns are better.

Charge!

Charge!

Do I have to remind you, bro, that your antlers fall off every year?

So the next year, they grow back bigger and with more points.

What'’’s your point?

Ha!

Horns always stay on, and get a little bigger every year.

(Grunting) Uh-oh.

Are you thinking what I'’’m thinking, bro?

Yeah, I think I'’’m thinking what you'’’re thinking.

BOTH: We'’’re stuck!

Okay, okay, let'’’s both pull backwards on three.

BOTH: One, two, three.

(Both straining) Whoa!

Whoa!

Huh?

Aww, I don'’’t want to play anymore.

Hey, get these antlers off of me!

We moose shed our antlers.

What can I say?

Deactivate.

(Grunting) Oh.

Hey, guys.

Well, at least you showed us the difference between horns and antlers.

We did?

Yeah.

Horns are permanent and keep growing.

Antlers are temporary.

They fall off and grow back bigger the next year.

Yeah.

We did.

Good job, bro.

Hey, Wild Kratts, look at this!

Your horn and antler skirmish prompted a question.

Come see.

It'’’s from Ronan, and he'’’s got a good one for you.

Hey, Wild Kratts, I was just thinking about the whale with the horn.

What about him?

How come you'’’ve never had an adventure with the narwhal?

What?

We haven'’’t?

No, we haven'’’t.

Well, we'’’ve got to.

Narwhals!

That'’’s today'’’s creature mission: to discover the horned whale.

Whoa, whoa, wait.

That'’’s a drawing.

Yeah, an imaginary drawing.

(Laughing) Yeah, let'’’s not go on a wild goose chase now.

What are you talking about?

Narwhals are real.

AVIVA: What?

Like a unicorn of the ocean?

You'’’ve got to be kidding.

And those are just old drawings, not photos.

Come on, I can'’’t believe a narwhal actually exists.

Wouldn'’’t its horn get tangled up in seaweed?

Good question.

And the only way to answer your questions is to fly to the Arctic and find some narwhals.

KOKI: Arctic?

We'’’ve got some Wild Kratts kids up there.

Hi, Wild Kratts.

Hey, Nua.

Have you ever seen a whale with a horn?

Have you ever seen a squirrel with a tail?

BOTH (Laughing): Good one.

I'’’ve seen many narwhal.

They'’’re called tuugaalik.

At this time of year, many gather in the bay not far from my village.

Okay, that settles it.

We'’’ve got to go, and now.

Jimmy?

Taking off.

I still have to see it for myself.

Yeah, me too.

Me too.

Me too.

JIMMY: Hey, what'’’s that at 12 o'’’clock?

MARTIN: That could be a pod of narwhals.

And there could be about 20 in a group.

Maybe up to a hundred.

Jimmy, set the Tortuga down.

JIMMY: You got it.

Hi, Wild Kratts.

Hey, Nua.

It'’’s good to see you again.

Hi, Aviva.

Where are Martin and Chris?

MARTIN & CHRIS: Whoo-hoo!

(Crashing) Hey, Nua.

How'’’s it going?

I'’’m good, because the narwhals are right over there.

Look.

See any dorsal fins?

Nope, because narwhals don'’’t have them.

How about horns?

Not from here.

Let'’’s get in there and find out.

♪ A narwhal!

No horn.

Probably a female.

Yeah, since all males have them, but hardly any females do.

Oh, yeah, I know you know that.

I was just telling my brother over there.

That'’’d be me.

Take us to your pod.

Ha-ha!

Any sign of a horn?

Nope, just a lot of narwhals.

Well, we might be here a while.

A narwhal can hold his breath for 20 minutes.

That'’’s a lot longer than we can.

Let'’’s wait for them up top.

No horns yet, but check out how narwhals breathe.

Yeah, that'’’s a blowhole.

It'’’s cool how it works, huh?

When the narwhal surfaces, the blowhole opens.

Old air is pushed out.

CHRIS: Then new air is breathed in.

(Laughing) Blowholes blow me away.

(Laughing) Yeah, but where is that legendary narwhal horn?

BOTH: Whoa.

We'’’ve got to get to that horn.

Come on.

Pardon me.

Excuse me.

Coming through.

Need a little room here.

Coming through.

Excuse me.

Pardon me.

Whoa!

MARTIN: Unbelievable!

It does exist.

(Laughing) Told you.

The horned narwhal is... AVIVA: Increíble.

Incredible.

That horn is almost 10 feet long.

MARTIN: It'’’s almost as long as the entire body.

(Laughing) Wow.

Ow!

Hey, little guy.

I'’’m saying that to a baby animal the size of a couch.

(Laughing) Hey, when is your horn going to start to grow?

Okay, okay.

I'’’ll think of a name for you.

Hmm, let'’’s see.

Look.

Another narwhal horn.

They'’’re facing off.

Whoa!

We'’’ve got a narwhal battle!

Oh, wow.

I'’’ve got to get to work on this Creature Power Suit.

MARTIN: That'’’s what narwhals use their horns for.

To battle for control of the pod.

To be the top narwhal.

The narwhal is the only type of whale, dolphin or porpoise, that has a horn.

MARTIN: Oh, wow.

I can'’’t wait to have that creature power.

Oh, yeah!

Then we could battle each other, bro.

CHRIS: Aviva, please hurry programming that narwhal power disc.

Okay, okay, hold your horses.

But you guys have to stop rushing me.

If I rush too much, I could make a mistake.

This is highly technical, sophisticated programming.

It'’’s not like baking cupcakes.

(Oven dinging) Oh, sorry, Jimmy.

Careful, Aviva, or you might not get one.

Jimmy, set your cupcake timer and get to the teleporter, because here come the narwhal power discs hot off the power press.

What?

Huh?

Aah!

Whoa!

Energize.

Whew, got '’’em.

BOTH: Yeah!

Oh, don'’’t worry, buddy.

I'’’m still thinking of just the right name for you.

But first, we have to...

BOTH: Activate narwhal powers!

Awesome!

Awesome!

Aw, there'’’s no horn.

Aw, there'’’s no horn.

Que?

Aviva, there'’’s no horn.

What are narwhal powers without a horn?

How could you forget the horn?

Maybe you guys are baby narwhals.

They don'’’t have horns either.

(Laughing) I told you not to rush me.

I thought the DNA from the narwhal, when you touched it, would be sufficient to grow the horn.

Apparently not.

Since the horn is such a unique feature, we should do more investigations.

We have to look more closely at the horn and at how it grows.

I need more data, which means you guys have got to get out there and make some observations.

But it'’’s going to be so embarrassing swimming with narwhals, in narwhal power suits, with no horns.

Deal with it.

BOTH: Whoa!

(Laughing) Good luck, Kratt Brothers.

Come on, bro, Let'’’s figure out the puzzle of the narwhal horn.

Yeah, and get the info that will grow horns on our narwhal power suits.

Ah-ha!

I had no problem with the horns on my cupcakes.

(Sniffing) Mmm, those smell good.

Aww, we'’’re getting jostled a lot.

That'’’s what I was saying.

In these narwhal power suits, as boy narwhals without horns, we'’’re not getting any respect.

Ow.

I think you'’’re right, bro.

Hey, wait a second.

The horn isn'’’t growing out of the narwhal'’’s forehead.

It'’’s growing out of the left side, above his mouth.

Ow!

This guy'’’s too.

Right.

It'’’s actually growing out of the upper jaw and protruding through the skin.

It'’’s a special tooth that grows super-duper extra long.

So if a narwhal horn is actually made of a tooth, then this horn is really a tusk.

Thank you.

So that'’’s where the mistake was.

No wonder that horn activation malfunctioned.

Because technically, that horn isn'’’t a horn at all.

It'’’s a tooth!

A tusk!

Of course.

Tusks.

Tusks are teeth that protrude from the mouth, like walrus and warthogs.

Or through the cheeks, like elephants and narwhals.

Where the tusk grows out of the jaw through the cheek area and out through the left side of the narwhal'’’s face.

This is exactly what I needed to know.

MARTIN: Soon we'’’re going to have a horn-- Oh, I mean tooth-- Tusk.

Tusk, tusk, tusk, tusk, tusk.

Yeah, we'’’ve been calling it the wrong thing the whole time.

We'’’ve got to remember it'’’s a tusk.

Tusk, tusk, tusk.

BOTH: Tusk, tusk, tusk, tusk, tusk... Oh!

Hey!

So how old are you narwhals when you grow your tusk, anyway?

How old are you now?

About 2?

Hey, what'’’s this?

Whoa, your narwhal tusk is growing.

(Laughing) Congratulations!

I'’’m going to name you Little Tusker.

Whoa, Little Tusker.

You are growing a tusk.

Awesome.

The narwhal power disc is complete.

Thanks, Aviva.

Now that I have the programming right, the narwhal DNA should direct a tusk to grow from the left side of your helmet.

Jimmy?

But I'’’m icing the cupcakes.

Incoming.

Ah!

Hold on.

Teleport.

(Groaning) Out with the old.

In with the new.

Okay, Little Tusker, let'’’s try this again.

And hope we get a tusk this time.

BOTH: Reactivate narwhal powers.

Yes!

Whoo-hoo!

Now this feels right.

These are incredible.

And, you know, now we can swim through the narwhal pod with lots of confidence.

And do you know what else?

Oh, yeah, and we don'’’t even have to do the-- "are you thinking what I'’’m thinking?"

thing, because this is so obvious.

En garde!

Touché.

(Both laughing) Wow, this is awesome!

Ha!

Gotcha!

Take that.

Huh?

What'’’s that?

I don'’’t know.

It looks like an old Inuit carving of a narwhal.

BOTH: Two tusks?

This must be make-believe.

A narwhal with two tusks?

Can this be true?

Wow!

Cool!

That is a beautiful carving.

And you found it at the bottom of the sea.

So it'’’s a treasure.

But look closely.

Notice something really cool about it?

ALL: Two tusks!

But narwhals only have one.

A two-tusked narwhal?

My grandfather talked of a very rare narwhal with two tusks.

Did he ever see one?

I think he did.

He said so.

Sometimes these sculptures have markings.

Like a signature.

There.

That'’’s his marking.

My grandfather made this!

ALL: Whoa!

I can'’’t believe you found my grandfather'’’s lost carving of a two-tusked narwhal.

Thank you, Kratt Brothers.

Sure, Nua.

You'’’re welcome.

No problem.

I ill can'’’t believe we found it.

Your grandfather was an amazing carver.

This is truly a work of art.

You know what else this means?

Uh-huh.

There could be a real two-horned narwhal out there somewhere.

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

I'’’m thinking there'’’s no doubt we'’’re thinking the same thing.

Today'’’s new creature mission is find the mysterious two-tusked narwhal.

Why am I not surprised?

My grandfather told me that they are very rare.

Only one in every 500 have two tusks.

Only one in every 500 narwhals have two tusks?

Considering that there were two male narwhals in this pod... Plus Little Tusker.

Oh, but he'’’s not full-grown yet.

And that each pod covers thousands of miles of open sea.

Oh, this mission of finding a two-tusked narwhal is going to be a real challenge.

Finding a two-tusked narwhal in the Arctic is like finding a needle in a haystack.

BOTH: But we'’’ve got to try.

Okay, so how do two tusks happen?

Hmmm, if the left tooth of the narwhal always grows into a tusk... Then maybe sometimes, in rare cases...

The right tooth of a narwhal must grow as well.

That must be it.

That has to be it.

Uh... one other question.

Do you think these horns have any defensive capabilities?

I don'’’t know.

Why?

Because there'’’s an orca right behind you!

Ah!

CHRIS: There'’’s no way a narwhal can outswim an orca.

Orcas are too fast.

Take evasive maneuvers.

Look!

A narwhal!

In there!

Whew!

Whew!

Whoa!

Whoa!

You know, both orcas and narwhals are technically not whales.

They'’’re actually porpoises.

But either way, they can'’’t hold their breath forever.

They have to come up for air sometime.

Okay, now with narwhal powers, we have enough air to stay underwater for about 20 minutes.

CHRIS: And the orca seems to know that we narwhals can hold our breath longer than an orca.

BOTH Whew!

Whoa, a cave in an iceberg.

Hey, let'’’s see where it goes.

BOTH: Wow!

CHRIS: What an awesome underwater cave!

(Loud trumpeting) Huh?

What was that?

BOTH: The two-tusked narwhal!

This is such a rare and amazing creature.

And one of our best discoveries yet.

A left and a right tusk.

Each must at least 10 feet long.

CHRIS: He is old too.

Near the maximum age of 115 years old.

And no wonder he'’’s lived that long.

He knows the tricks of survival.

Like how to avoid orcas.

He is one wise old narwhal.

Little Tusker.

Hey, did you follow us?

That tusk.

If you'’’re going to bump me don'’’t bump me with the left side that has the tusk.

Bump me with the right side, the side with no tusk.

Ow!

I don'’’t believe it.

This little guy is a two-tusked narwhal!

(Laughing) Amazing.

He was right in front of us the whole time.

Yeah, but those little two nubs aren'’’t that obvious.

It'’’ll take years to grow into impressive tusks like that.

Now, of course, I'’’ve got to rename you Two Tusker.

Come on, let'’’s get back to the surface and show the others.

ALL: Oh, wow.

Cool.

What a day.

Yeah, first we learn that narwhals are real.

Then find my grandfather'’’s lost carving.

And then see an actual two-tusked narwhal.

We'’’ve got to celebrate.

I'’’ll get the cupcakes.

Hey, bro, if one out of 500 male narwhals have two tusks, then if we activate our Creature Powers Suits 500 times, we could get two tusks too.

Reactivate.

Aww, still one tusk.

Hmm.

Try again.

Reactivate.

Well, every time we don'’’t get two tusks, our chances get better the next time.

Reactivate.

Aww.

Reactivate.

CHRIS: Reactivate.

Reactivate.

Aww.

CHRIS: Reactivate.

Uh, this might take a while.

I'’’m glad we'’’ve got cupcakes.

MARTIN: Reactivate.

Reactivate.

Reactivate.

Reactivate.

Reactivate.

CHRIS: Reactivate.

(Snoring) Reactivate.

Reactivate.

Reactivate.

Finally!

It worked!

Two tusks!

Yeah!

You did it, bro!

(Laughing) Keep going, bro.

You got to be close to 500 by now.

Reactivate.

(Laughing) Two tusks!

Two-tusked narwhal power!

Whoo-hoo!

(Both laughing) Yeah!

Whoo!

MARTIN: See you later, Two Tusker.

CHRIS: See you soon, buddy!

(Both laughing) Oh, now this is a white-tailed deer, with an impressive rack of antlers there.

Look at those antlers.

One, two, three, four, five, six, seven points.

The bucks use them for fighting other bucks, for mating rights.

And every year in the fall, they battle and battle.

They have through the winter these amazing antlers, but then, sometime in the winter, they fall off.

And then next summer, the antlers start growing again.

This is a one-year-old buck.

See his little antlers?

That'’’s his first set of antlers.

And every year that he grows new antlers, they'’’ll get bigger and bigger and bigger until, when he'’’s an older male, he'’’s got a big rack.

And here'’’s the doe.

A beautiful female deer, but no antlers.

Does don'’’t fight each other.

There'’’s no reason for them to have antlers.

So why put the energy into growing a new set of antlers every year?

For bucks, though, antlers are really important.

CHRIS: Lots of antlers in the caribou herd.

This is actually a female caribou.

With caribou, females have antlers too, and their antlers will fall off in the spring, after they have their babies.

Now check out this caribou.

Where are the antlers?

This is actually a male caribou that has the greatest antlers of all.

But they'’’ve fallen off.

They fall off shortly after mating.

Musk ox have horns.

Horns that keep growing.

They get bigger and thicker on the top every year.

And those horns are important, because the male oxen have big, ramming head battles.

Females have horns too, and the females and the males use the horns for defense.

And the defense of the musk oxen is awesome, because they form a ring, horns facing outwards, So any attacking wolves have to meet horns no matter what angle they come in on.

Horns are an awesome creature power.

Keep on creature adventuring.

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