Do you hear that?

Dustin!

Yes, it's Dustin.

I'd know his sound anywhere.

Dustin!

Don't move!

Stay right there, Dustin.

We're on our way.

Stay put, little guy.

It sounds like we're getting closer-- Whoa!

Hal!

Are you all right?

I'm good.

It's okay, I fell on my head.

(Rattling continuous) Uh, hello?

VOICE: Uh, hello?

What the who?

VOICE: What the who?

Who the what?

VOICE: Who the what?

Aye, aye, aye.

VOICE: Aye, aye, aye.

I think someone's copying everything you say, Hal.

(Tweeting) Oh, it's a mockingbird.

Of course.

Of course.

Oh, that makes sense.

Hi.

Hi.

Oh, yeah.

Mockingbirds are experts at listening to nature and imitating what they hear.

All right, mockingbird, let's hear some of your best imitations.

What do you got?

Oh, sweet.

I've got to record this.

(Tweeting) (Imitating rattling sound) Wait a minute.

That's the sound Dustin makes.

So it wasn't Dustin we were hearing.

It was the mockingbird.

Oh, that's a bummer.

Oh!

It is pretty good, though.

But if this bird can imitate Dustin's sound, well, that means it heard Dustin.

Oh!

Do you know where my grasshopper friend is?

Can you take us to him?

Wait, wait, wait, wait!

I can't follow you up there.

Never fear.

I can keep up with that bird.

Tallyho.

(Screaming) Eureka!

We've found him.

Dustin!

There you are.

Oh, I'm so glad we found you.

I was so sad, and now I am so happy.

Come on, we've got to get you back to the race.

It's about to start.

(Chirping) Oh, it still seems like something's bothering him.

Yeah.

Why does he keep making that sound?

Huh.

It says here that male grasshoppers make that sound to attract female grasshoppers.

ALL: Oh.

Hey, look, there's another grasshopper.

So I guess it worked.

Oh, Dustin was just looking for his friend this whole time.

Now she can come to the race and cheer him on.

ALL: Hooray!
