Hey, it's the Kratt Brothers here.

I'm Chris and there's my brother Martin.

I put a creature that makes a special sound right here in this log.

Let's see if Martin can tell who it is.

Hey, Martin, check it out.

What's going on?

Put your hand right here in that hole.

What?

Trust me.

(Laughing) All right.

(Creature squealing) Whoa!

(Squealing and chirping) That sounds like something's going to rip my hand off.

I know.

It sounds really ferocious.

But we got to find out who it is.

(Creature squealing) Oh!

Oh!

Just kidding.

A sugar glider.

Now that's a pretty scary sound for such a cute and friendly creature to make CHRIS: Sure, gliders only make that sound when they're surprised.

And now that he knows it's us, he's not afraid.

He's our pal.

It just goes to show you, you can't judge a creature by the sound it makes.

(Laughing) A sugar glider is a type of possum from Australia.

They're gentle creatures that leap and glide around the forest, searching for food like sap, bugs and even nectar from flowers.

(Laughing) Sometimes you just have to get to know a creature.

Find out more about them to understand what they're really like.

Hey, I know another creature who's misunderstood.

She lives on an island off the coast of Australia.

Who roams around at night making mysterious sounds.

Imagine if we could prowl with that growl.

BOTH: What if?
