That's me, Fred the housecat.

When my family leaves for the day, I don't just sit inside watching the world go by.

I become...

Oh, yeah!

It's spring.

Woo-hoo!

Spring.

♪ I just love spring it makes me want to sing ♪ HAL: Oh, I love the spring too.

I love the sights, and-- Oh, look.

The geese are back now that it's warm again.

Hi, Goosie.

It's me, Hal.

So good to see you again.

Hi, Hal.

OTHER GEESE: Hal, Hal, Hal!

Whoa!

Oof.

Oops, sorry, guys.

I was just so busy looking at the sights of spring.

I love all the smells of spring.

Oh, Lily of the Valley.

My favourite.

(Sniffing) Mmm, so sweet.

Yes, the sights, the smells.

And once we arrive at the pond, we will hear one of the most amazing sounds that spring has to offer.

A brook babbling?

A robin chirping?

A rock, rocking?

No, my friends: a bullfrog croaking.

Oh, yeah.

A bullfrog's croak is one of the most incredible, unmistakable sounds in nature.

Oh, man.

You can hear those bullfrogs from so far away.

But today we're going to hear it up close, Squeeks.

Spring sounds await.

Tally-ho!

ALL: We're here!

Shh, shh.

Let's listen.

(Bullfrogs croaking) Oh, those are the spring peeper frogs.

I hear my green frogs in the house.

(Croaking) NATURE CAT: There it is.

I give you the majestic sound of the bullfrog croak.

Whoa.

They are loud.

Okay, wait.

I want to try.

(Clearing throat) ♪ Mi-mi-mi-mi ♪ Let me try.

Ribbit, ribbit.

Wait, that's not good.

(Scratchy) Ribbit, ribbit.

That's better.

Scary.

Sounds like a dragon more than a frog.

Hold on.

(Screechy) Ribbit, ribbit!

There we go.

That's a frog.

Keep practising, sweetheart.

HAL: Ribbit!

Or maybe right now we just listen to the frogs.

Okay-dokay.

Wow.

(Croaking) Look at what happens to his throat when he croaks.

(Croaking) Well, hi there.

What is your name, bullfrog friend?

My name is Warren.

Well, Warren, might I inquire why you're not croaking on this fine spring day?

I just don't feel like it today.

You don't feel like it?

But it's spring, and all your other bullfrog friends are croaking.

(Sniffling) (Crying) Was it something I said?

(Sobbing) Oh, no, please don't cry.

No, please.

If you do, I'm going to, too.

(Sobbing) Why are we crying?

I have no clue.

But it felt kind of good.

I know why I'm crying.

(Blowing nose) Tell us, Warren.

Uh, it's really bad.

Did you accidentally bury your friend's favourite kite but then forget where you buried it?

Because that would be terrible.

I've never done that.

Uh, no.

That's not what it is.

I, um-- I can't, uh-- (Clearing throat) I can't croak, okay?

That's what it is.

I have an inability to croak.

I thought all bullfrogs could croak.

I cannot croak.

But isn't croaking so important for bullfrogs?

It is the most important thing, next to hopping.

Look at those frogs over there.

Each one is telling everyone else, "This is my space.

I live here.

I claim it."

We don't have feathers.

We don't have all the things to say that it's our territory, so we got to do it with sound.

(Croaking) The other thing is croaking makes the girls take notice.

Look at Stuart over there.

Oh, Warren.

You, poor, poor frog.

Are you sure you can't croak?

Maybe it's not as bad as you think.

Yeah, come on.

Give it a try.

No, no, no.

I will not.

Oh, yes, you will, young bullfrog.

Don't give up.

That's what you want?

All right.

(Clearing throat) (Gibbering like a monkey) Oh.

Well, that wasn't so bad.

No, not bad at all.

It was very distinctive.

HAL: Wait.

Did you guys not hear that croak?

That was a terrible croak.

That was like, "Blehhh."

It was terrible.

Doesn't even sound like a croak.

You see?

I told you.

I am the worst croaker in the whole pond.

I have no space to call my own, and I'm never going to have anybody.

No girlfriend, no nothing.

I'm going to sit in a lily pad and be sad and lonely forever.

(Crying) Friends, we can't let this poor bullfrog be so sad like this.

We are going to help you become a better croaker, dear Warren.

Right, friends?

Of course.

You bet.

Yay for croaking!

But, um, how are we going to do that?

I don't know.

I mean, I'm a croak enthusiast, but I'm sort of a listener, not a doer.

Hey!

How about croak school?

Excellent idea, Daisy.

To croak school!

Now, the first thing we have to do at croak school-- Oh, pick me, pick me, pick me!

Hal, you have a question?

Can I move to another seat?

Absolutely.

Now, as I was saying, the most important-- Oh, oh, oh!

Hey.

Yes, Hal?

Another question?

Will there be a test on this?

No, there will not.

Now, as I was saying, the most important-- When is snack time?

And where's the bathroom, and when is snack time?

Hal?

Can we save the questions for the end of the lesson, bud?

Aye-aye, captain my captain.

Please continue.

(Snoring) Now, if Warren wishes to croak, all he must do is repeat after me.

Cr-- (Clearing throat) Cr-- Oa-- Oa-- And last-- And this one is very tricky-- K. K. Now, put that all together.

(Flatly) Croak.

Aha, I did it!

I taught Warren how to croak and on my very first try.

How you like me now?

Class dismissed.

Um, Nature Cat?

That's not how a bullfrog croaks.

Eh?

What's that, now?

Watch this.

(Croaking) (Snoring) Huh?

Wait a second.

What is it, Daisy?

What do you see?

Look at this bullfrog's throat when he croaks.

(Croaking) Whoa!

It blows up like a balloon.

Watch how it pushes the air through its throat so the throat bulges out like a balloon.

Hmm.

I have never tried that.

Ooh, try it.

Okay.

I'll try.

(Guttural grunting) (Croaking) You did it!

You croaked!

That was glorious.

Stupendous.

Did I?

Was that a croak?

I have no idea.

Now, let's get you back into that pond so that you can mark your territory and find a mate.

My worry is that, you know, is it loud enough?

You know, volume?

Don't worry, Warren.

You'll be great.

Go get 'em, Warren.

(Croaking) Come on, Warren.

You got to croak.

(Croaking softly) I don't think any of the other bullfrogs heard him.

Oh, no.

SQUEEKS: Wait, Warren!

Oh, Warren.

Don't give up.

I just can't-- I can't do it.

All those frogs have been croaking their whole lives.

I'll never be as loud a croaker as they are.

Maybe I shouldn't even be a bullfrog.

Nonsense.

You are a bullfrog, and a happy bullfrog you shall be.

Well, how?

Oh, oh, ooh!

Pick me, pick me, pick me.

Yes, Hal.

You can choose whatever seat you like.

No, Nature Cat.

I think I can help Warren.

I once lost confidence in doing something that all dogs do: howling.

It was a long time ago, and I had just gotten over a cold so I was a little out of practice.

(Raspy, breathy screeching) (Coughing) It was so embarrassing.

I thought I would never have the confidence to howl again.

But then my friends reminded me that I'm a dog, and howling is what dogs do best.

And they made me feel so good about myself and before you knew it, I was howling longer and louder than any other dog in the woods.

(Other dogs applauding) You've got to just get your bullfrog confidence, Warren, and you'll be croaking so loud aliens in space will hear you.

That's loud.

Yeah, but how?

What makes you feel most like a bullfrog?

What makes me feel most like a bullfrog?

This is good.

Um, I like hopping.

You know, hopping?

I've always, uh-- You know, when I was a kid I liked hopping.

You know, I would hop around.

So, I would-- My number one would be hopping.

Then hop you shall, and hop until your bullfrog confidence is up, up, up.

And we'll help.

(Croaking) You sound fantastic, Warren.

Are you feeling confident yet?

I am!

Listen to this.

(Croaking loudly) I think I'm ready to claim my own space.

You can do it, Warren.

(Other frogs croaking) (Croaking loudly) That was glorious.

Bravo, bravo!

(Croaking) Hey, guys?

I think it's working.

(Both croaking) Way to go!

Good for you.

Go on.

Oh, yeah.

HAL: Yay for croaking!

Well, I think our work here is done.

Now all that's left to do is listen to the melodious sounds of the frogs.

(Croaking continues) Uh, I'm sorry.

Excuse me, Mr.

Nature Cat.

One final question.

Will there be a test on this?

No, Hal.

Okay-dokay.

(Croaking) Man, oh, man.

It sure is hot today.

This summer heat won't get the best of us.

Think cool thoughts, my friends.

Okay.

Ice cube.

Iced tea.

Vanilla ice cream.

(Slurping) Hey, guys?

I know how to stay cool today.

I'm having a pool party.

Um, did you say "pool party"?

Yeah, now, that's how we get cool.

Smart.

DAISY: Sweet idea, Squeeks.

Wait.

Don't you need a pool for a pool party?

You sure do, and I found one.

Yesterday.

You found a pool?

What?

Well, technically it's more of a puddle.

A puddle?

Yeah, a puddle pool.

And my puddle pool party is just what we need today.

It's going to be glorious!

We'll swim.

We'll frolic.

We'll play with those weird little pool noodles.

Wow!

So, who's ready for my puddle pool party?

We are!

We so are.

And how 'bout you, Nature Cat?

Thank you, but you know, it means I have to get wet and I don't really like-- SQUEEKS: Great.

Come on.

Huh?

Puddle pool party, here we come!

What she said.

Last one in is a mouldy cheddar.

Oof!

Hey, my puddle pool.

Where's my puddle pool?

Are you sure this is the spot, Squeeks?

Well, I thought so.

Um, yeah.

Yeah, this is definitely the spot.

Well, where did it go?

It was right here yesterday.

I don't understand.

It's like the puddle just disappeared into thin air.

Oh, disappeared, eh?

Sounds like magic.

And if we're dealing with magic, then we need-- (Imitating voice echoing) The Great Haldini.

THE OTHERS: Oh!

Ah, we just need a trick to make your puddle pool reappear.

Watch and be amazed.

Give a hug, give a cuddle.

Huh?

Now bring Squeeks back her wet pool puddle.

Ta-dee!

Huh?

Wait, maybe I said the wrong magic words.

I don't know.

I don't remember what I did.

Yeah, thanks anyway, Hal.

This just doesn't make sense.

I found the puddle right here a few days ago.

Maybe it just soaked into the ground.

That's what happens when I water my garden.

But look how hard the ground is where the puddle was.

It doesn't look like the water would just soak in.

I'm so sorry, Squeeks, but maybe we can find something else to do today.

SQUEEKS: Yeah, okay.

I guess we just won't have my awesomely super-cool and super-wet puddle pool party.

It'll be all right.

(Crying) Puddle!

Where did my puddle go?

Oh, Squeeks.

Although I thoroughly dislike puddles of water, I thoroughly dislike seeing you sad way more.

(All crying) What he said.

(Wailing) (Crying) Uh, excuse me?

What is everyone so sad about around here?

Oh.

Why, hello there, Mr. Earthworm, sir.

You see, our friend here is just a little upset.

Her puddle of water disappeared.

Poof!

Gone.

Gone for good.

I'm getting through it, but barely.

Gone for good?

(Chuckling) And what, pray tell, is so funny about that, Mr. Earthworm, sir?

Water is never gone.

Water and puddle will be back.

Bye-bye.

Wait.

How do you know the water will be back, Mr. Earthworm, sir?

'Cause it always comes back.

It's all part of the water cycle.

Motorcycle?

I love motorcycles!

Vroom-vroom!

Vroomety-vroom.

Not motorcycle; the water cycle.

(Sighing) Don't you know anything about the water cycle?

I know about water bottles, but not water cycles.

Well, let me explain.

You see that water in your bottle?

Why, yes, and it is very refreshing.

(Gulping) And it's pretty much been around since Earth began a long, long time ago.

Eee-ew!

That's old water.

Yes, sirree.

It seems to go away but it always comes back.

Whoa.

How is that even possible?

Because the water moves from the ground, up to the sky and back down to the ground again.

You just blew my mind, earthworm.

Nature recycles the water to keep the rivers flowing, the plants growing, and the animals healthy and glowing.

How?

I mean, why, what and how?

I'm so confused.

Can you just sing a song about it, please?

Let's tell them about it, worms.

♪ Evaporation, condensation precipitation ♪ ♪ Evaporation, condensation, precipitation ♪ ♪ That's the water cycle ♪ ♪ Ever since the Earth was formed ♪ ♪ That's the water cycle where water gets transformed ♪ ♪ When water is heating, getting hotter ♪ It will change just wait ♪ ♪ It turns to gas called water vapour ♪ ♪ It will evaporate ♪ Wow!

The water changes to vapour?

It's invisible?

Whoa.

It must be magic.

Nope, it's evaporation.

♪ That's evaporation that's evaporation ♪ ♪ Go tell the world go tell the nation ♪ ♪ That's evaporation ♪ ♪ Vapour rises and gets cooler ♪ ♪ Then watch and be aware ♪ ♪ The vapour changes back to tiny droplets in the air ♪ The water changes again?

MR. EARTHWORM: That's right.

From a vapour back to water droplets.

HAL: That must be magic.

Nope, that's condensation.

Nope.

Well, this dry, hot weather may be perfect for evaporation, but this worm wants to get back underground where it's cool and moist.

Catch you around the bend.

Thank you, Mr.

Worm, sir.

I'll talk to you soon.

Have fun.

Be careful, okay?

And send me a postcard.

Let me know how you're doing.

I get worried.

Do you guys have any idea what this means?

What, Squeeks?

What goes up will come down.

My pool puddle will be back.

Yippee!

Pool puddle.

Unh-unh-unh.

HAL: Yes!

(Sighing) Wait.

So, is your puddle back yet?

Not yet.

Okay, how about now?

Is it back yet?

Still nothing.

Hmm.

Something tells me that puddle won't be back until the next time it rains.

BOTH: When is it going to rain?

Hey, guys.

Remember what the worm said?

When the water vapour cools and changes back into tiny drops of water, it forms clouds.

You mean condensation?

That's it.

Let's go look for signs of condensation so we know when the rain is coming.

Good idea.

Let's look for clouds.

Onward and cloud-ward!

ALL: Oof!

♪ (Panting) Look, clouds!

HAL: Oh, it looks like a horsey.

DAISY: It's better than a horsey, Hal.

Those tiny droplets are growing and making a cloud.

Oh, no.

When those droplets get big enough they'll fall from the sky.

And do you know what that means?

Precipitation.

No.

It means wet cat.

Whoa!

(Teeth chattering) Oh, happy day.

It's raining.

Whoa, just think.

This water has been around since the Earth began.

Ohh.

Oh, welcome back, water droplet.

Oh, and you too, water droplet.

And that one and that one and that one and you, too.

It's me, Hal, again.

We missed all of you.

I love the water cycle!

(Teeth chattering) Oh, thank goodness.

The wet, wet, wet rain has ceased.

That means it's time for-- Puddle pool party!

Last one in is a mouldy cheddar!

You were right, Squeeks.

This puddle is a lot of fun.

Come on in, Nature Cat.

The water is fine.

And so, so cool.

Ahh.

NATURE CAT: Uh-huh.

Okay, I'm in.

(Chuckling nervously) MR. EARTHWORM: That's not in.

This is in.

Yee-haw!

Ugh!

Now I'm all wet.

Don't worry, Nature Cat.

Soon all the water will turn to vapour and then you won't be wet anymore.

Hey, that's right.

Well, in that case, whee!

(Giggling) Let's hear it for the water cycle!

(Everyone cheering) All hail the water cycle!

DAISY: Oh, yeah.

Water cycle.

Water cycle.

Oh, yeah.
