Hey, D.W.!

Hey!

Whoa... (crash) ARTHUR (nervously): This movie isn't scary at all.

(nervously): I've never been less scared in my life.

(banging upstairs) What was that?

Did you hear something?

I hear a thump, thump, thump!

Oh, wait, that's just my heart.

If you two can't handle scary movies, then you shouldn't have... (rattling upstairs) (screaming) It's coming from upstairs!

But the only ones up there are Kate and Mei Lin.

(whispering): On the count of three.

One, two, three!

BINKY: I told you it was nothing.

Let me guess: you thought it was aliens.

Well, something knocked those books off the table.

Come on, let's go finish the movie.

(rattling) (door closes) Okay, you can come down now.

I say!

What was that all about?

Oh, you know big kids.

Always letting their imaginations run away with them.

Now, who's ready for a little jaunt into outer space?

What did you say your name was again?

Dr. Yowl.

Canine of the cosmos, mutt of the Milky Way.

And Pal's cousin.

At your service.

You never told me you had a cousin.

He's a distant cousin.

I live four billion miles away on the planet Pluto.

Although our status as a planet was recently revoked.

Now we're just a dwarf planet.

Oh, the ignominy.

(theatrical crying) You poor thing.

It's just an act.

Yowl always was a ham.

Oh, speaking of ham, I have a doozy of one in the Barcdis.

We're having a party back home, and you're all invited.

The Barcdis?

It stands for Ballistic Astro Rocket for Carrying Dogs In Space.

Isn't she a beauty?

I'd love to go to a party on Pluto.

It does seem rather exciting.

I don't know, Kate.

It sounds risky.

What if he doesn't get us back by supper?

No offense, Yowl, but you're not the most reliable dog... Sweet mother of dog!

That is a big ham.

Then it's settled.

All aboard.

Next stop, Mercury.

I thought you lived on Pluto.

Oh, we just have to make a few stops along the way.

DR. YOWL: Mercury is the planet closest to the Sun, so it's a bit toasty out there.

I knew this was a bad idea.

You and Mei Lin didn't bring any sunblock.

DR. YOWL: Not to worry.

I have just the thing to protect you from all the hostile environments we'll visit.

Hostile environments?

Turn this ship around right now!

Fortunately for us, the Plutonians have invented space snacks.

One little nugget, and you can safely go anywhere.

And they taste like chicken.

(crunching) Mmm, not bad.

So crunchy!

Could've used ketchup.

PAL: Oh, what an awful place!

MEI LIN: I think it's beautiful!

It's like a giant sandbox.

You could try enjoying yourself a little.

After all, it's not every day that you're on Mercury.

I know, but my cousin is a troublemaker.

He visited one Thanksgiving, stole the turkey, and guess who got blamed for it?

Maybe he's changed.

You should at least give him a chance.

(grunting) Whew!

I brought us here to bake the ham for the party.

In this heat, it should be ready in a few seconds.

You're right.

Perhaps I have misjudged him.

Should we, um, test it?

See if it's fully cooked?

I don't see why not.

Next stop, Venus.

The second planet from the Sun.

I left a toy on the surface last time I dropped by.

It won't take but a minute.

A dreadful place.

It's actually even hotter than Mercury, and it rains sulfuric acid.

Ah, here it is.

Right where I left it.

I say, why don't we have a bit of catch?

It's so rare that us Plutonians get a human to throw a ball for us.

All right, Kate, let's see that arm.

Not bad.

Of course, the fact that there's less gravity here than Earth helps.

Race you, Pal!

All right, Mei Lin.

Now it's your turn.

DR. YOWL: Leaping labradors!

You should play for the Grebes.

I'll get it.

(buzzing) This is Pluto, calling Yowl.

How goes your secret mission?

Have you convinced the subject to leave Earth forever?

(gasps) Pal was right!

Dr. Yowl is up to something.

PAL: Where's that ball?

I want to show Yowl my fancy paw-work.

I have to talk to you about him.

I know, I know, you want me to give him a second chance.

And I am.

He's actually rather fun.

Okay, play time's over.

There's just one more stop we have to make.

The fourth planet from the Sun-- Mars.

There it is.

The Curiosity Rover, which you earthlings put up here in 2012.

Why do you want that?

All dogs like to chase cars, even the ones on Pluto.

I thought it'd be fun for the party.

Come on, old sport.

Let's go grab it!

Faster, faster!

Woo-hoo!

Now we're cooking!

Faster, faster!

(coughing) PAL: Driving cars is even more fun than chasing them.

Kate, you have to try it.

Yes, you two go for a spin.

I want to show Mei Lin something.

Pal, you were right.

No, you were right, Kate.

I'm having a ball.

I want to explore the galaxy forever.

You do?

(sniffling) What's wrong?

I overheard the Plutonians' plan.

They want to convince you to leave Earth forever.

I knew we couldn't trust that conniving cousin of mine.

(alarm blaring) (gasps) They've left without us!

If Yowl's trying to get me to move to Pluto, he's going about it in a rather odd way.

DR. YOWL: That's Jupiter, the fifth and biggest planet in the solar system.

Then there's Saturn.

Those rings are actually composed of bits of ice.

Why aren't we stopping?

You said we'd get ice cubes and then turn around and pick up Pal and Kate.

Oh, did I?

I'll pick them up later.

Besides, it's really you who everyone wants to meet.

Okay, we're stuck on Mars with no way to get off.

What should we do?

How about panic?

Panic sounds good.

We're doomed!

Nonsense.

We just have to use our heads.

He could've at least left us the ham.

Wait a minute.

What's that in your hand?

Hm?

Oh, it's Dr. Yowl's magic chew toy.

I must have taken it by accident.

That's what he used to make the Barcdis appear.

Quick, press some buttons.

Oh, now I've got doggie pox.

Try another one.

Aha!

It must be his back-up Barcdis.

Quick, let's rescue Mei Lin.

Can we bring the Rover?

It's so much fun..

Please, please, please?

Okay... KATE: That's Uranus and Neptune, gas giants and sister planets.

PAL: Speaking of gas, let's step on it.

We've almost caught up to Yowl.

(dogs barking excitedly) DR. YOWL: Pal, Kate!

I was, uh, just about to go back for you.

Stand back from her, you ruffian!

Mei Lin.

Are you all right?

I'm fine.

Your extended family is really nice.

Welcome to Pluto, Pal.

This is your cousin Sal, and Cal, and Val.

And of course me, your Uncle Al.

I'm sorry Dr. Yowl got carried away, but there was a simple reason.

Because Pluto is so small, it has very low gravity, much lower than Venus's.

And that means...

I can throw a ball a really, really long way.

(barking excitedly) We didn't mean any harm.

We just wanted someone to play fetch with.

But we'll let her go.

Maybe you don't have to.

But I'll need your help.

Why not me?

I'll help you.

Ball, ball!

It's mine!

I call it.

Before we say goodbye to our visiting friends, let's say thanks for Kate's idea to transform the Mars Rover into a Plutonian ball thrower.

(barking excitedly) Pal, it's time to go.

Already?

But I was having such a good time.

Maybe you'd like to stay, after all.

It's okay with me if that's what will make you happy.

BINKY: What a silly movie!

I can't believe you two were so scared.

(banging upstairs) Ah!

It's back.

Weird.

Everything seems fine.

Come on, Mei Lin.

Let's get out of here.

This place gives me the creeps.

(door closes) Pluto had everything you could want, Pal.

Everything except you, Kate.

And now a word from us kids.

Hi, my name is Marley, and I'm in Miss Kaplan's third grade class.

Kate and Pal traveled through the solar system and learned about the planets.

Today, we're learning about the planets too.

Can anybody tell me the order of the planets from the Sun?

Mercury, Venus, Earth... Mars, Jupiter... Saturn, Uranus, Neptune.

(applause) What we are going to be doing today is we are going to be creating a commercial to try to get someone to visit your planet.

Miss Kaplan assigned us planets, and then we did some research.

Did you know that Jupiter could hold more than 1,300 Earths?

It's got 62 moons and it's got rings too.

It's Saturn.

We talked about the things you should bring when you visit our planet.

Mars has some volcanoes, so maybe we'd need some hiking boots.

Mercury is closest to the Sun, so they need sunglasses.

My planet is Jupiter.

I have this in case of a storm.

Then we got ready to put on our commercials.

Jupiter is the stormiest planet in the solar system.

Go to Jupiter if you like storms.

(sings jingle) Come on down to Venus.

It's very hot, so bring sunscreen.

♪ Venus, Venus, so hot it's cool.

♪ I'm Saturn.

Don't bring your jewelry, because we got rings.

Come to Mars, it's the next planet from ours.

Call 555-MARS to book your vacation.

You'll never want to leave.

What planet would you like to visit?

ALL: Bye!

And now, back to Arthur.

(with French accent): In my career as a consulting detective, I have unraveled many a tricky knot, but none so knotty as The Case of the Disappearing Dummy.

What a dastardly deed!

Your most entertaining puppet, Wallace, stolen from under the nose.

(English accent): Yes, well, uh... Worry not, Bastings.

I, detective mastermind Virgule Watteau, shall not fail you.

Ah, well, you see... No need to thank me.

As my oldest friend, I'm happy to help you discover the culprit.

Already the brain cells, they are working at the speed of lightning.

I hired someone else.

Even at this moment, I am homing in on the answer.

Got another detective working, actually.

This is obviously the handiwork of... What did you say?

Just that I... Pip pip.

WATTEAU: The Gray Dove!

You return to the scene of your crime.

Actually, Watteau, I have a confession.

I hired the Gray Dove.

To do what?

To, uh, solve the crime?

Any problem with that?

Maybe.

Oh, yeah?!

Yeah!

Oh, dear.

Fern, there you are.

You'll never guess what happened.

(whispers): Someone stole Wally.

(gasps) I left him right here, but now he's gone.

Look, they left the case open.

What happened?

Checked lost and found?

I searched everywhere.

It's no use.

What's going on here?

I'll have to ask you to stay back, ma'am.

This is a crime scene.

Ma'am?

Crime scene?

Ma'am?!

Where were you?

I was looking all over for you.

I had a dentist appointment.

Well, when I couldn't find you, Binky offered to help.

Happened to be in the area and responded to the call.

He got a junior detective kit for Christmas.

Copy that, we've got a 1066 in progress, will update you as the situation unfolds.

Did you just talk into a fake walkie-talkie?

Ma'am...

I know.

It's a "crime scene."

Fern!

Please, sir.

I'll handle this.

I hope you're not leaving.

We have a crime to solve.

"We"?

Listen, the big PTA variety show is in two hours.

If we don't find Wally, that show is going to be minus one dummy.

I'll fill you in.

The vic is an eight-year-old male moose by the name of George Lundgren.

I know who George is.

The story I got is this.

All week, the teacher, Ms. Fink, had everyone leave their show props in the music room.

She didn't want anyone leaving anything they needed at home.

After school today, George found his case open.

His dummy had vanished.

(clarinet playing) Missing.

Gleeped.

El gone-o!

In other words, stolen.

I got that.

Luckily, I happened to have my new detective kit on hand.

Here's the way I figure it.

Someone else in the show must have been afraid George was going to be better than them.

So last night, they snuck in and stole the giraffe.

The question is, who?

That's a very good question.

It is?

Let me think about it.

You do that.

Meanwhile, I'll ID the perp using good old shoe leather.

A perp is a...

I know what a perp is.

Right.

Bye.

There was something strange about the sudden appearance of this new investigator.

A most interesting case, I have to say.

It was most wise of you to have retained my services, Mr. Bastings.

You know who did it?

I can tell you that whoever stole your diminutive friend must have gained access to your roof.

From there, it was a simple matter to lower down, enter through the window, lightfoot it across the rug, and purloin your puppet.

I say, that's most clever!

(feeble clapping) Wonderful.

I have but one question.

How would you know that the culprit came via the roof unless you were on the roof?

Uh... (stammering) Watteau, you're right.

It was the Gray Dove.

He did it.

Hm... (pencil scratching paper) Who are we spying on?

You got a bead on a perp?

No, probably just a wild goose chase.

Wild goose?

You mean one got into the room?

It sounds crazy, but maybe you're onto something.

Well, there's always a bunch of them near city hall.

Good thinking.

I'll go check.

I know you suspect me, but I didn't do it.

Huh?

Okay, I did take Wally out of his case, but I didn't steal him.

What are you talking about?

When was this?

Yesterday, after practice.

Hey, look!

What a relief!

That box is a real pain in the neck.

(laughing) Someone's coming.

FRANCINE: It was inside when Mr. Morris locked the door.

Then Binky must have come back later.

Huh?

Oh, nothing.

Thanks for your help.

Wally must be in his house.

Hello?

Binky?

Looking for something?

Oh.

No.

I mean, yes.

I mean... By the way, I know who stole Wally.

Really?

So do I.

BOTH: You!

What are you doing?

Making sure you don't run away.

Me?

Why should I run away?

Because you did it.

I figured it out when you sent me to look for that wild goose.

I should have known it was nothing but a trick.

Why on earth would I want to take Wally?

Uh... give me a sec.

I know.

So you could solve the crime and take all the credit.

Attention hog.

That's ridiculous.

Could you get us out of these now?

All right, but...

Uh, hang on...

There may be another mystery.

One about a missing key.

Binky!

It's gotta be around here someplace.

Or the school.

Or the town.

(sighs) Well, maybe you should have thought of that before you sent me over here.

That wasn't very nice, you know.

Well, it wasn't nice of you and George to leave me out.

He couldn't find you.

He didn't mean to hurt your feelings.

He was just worried.

You're right.

(sighs) Yeah.

Just wish my detective kit had fingerprint powder.

Then I'd know who took Wally from that dummy case.

Oh, that was Francine.

She was playing with it last night.

When she heard Mr. Morris coming, she must have... Left it on the table.

So that means...

It wasn't...

Exactly!

Run!

George claimed Wally was in his case every night.

Go left.

Other left, other left.

But last night, Francine left him out of the case.

Cement!

Everyone knew Wally was part of the show.

Everyone except one person.

A person with keys.

Pipe!

MR. MORRIS: You mean that giraffe?

That was part of the show?

Yes.

You know what happened to it?

Sure do.

I just figured it was one of the kindergarteners' toys.

GEORGE: Wally!

Good work, partner.

Sorry about calling you a thief and everything.

Yeah, me too.

I can't wait till we solve our next crime.

Thanks for finding me.

If I had to hear that "Itsy Spider" song again, I was gonna lose my marbles.

George, you're on!

That's our show.

Say goodbye, Wally.

Goodbye, Wally.

(applause) Oops.

FERN: We have to find that key now!

BINKY: Roger that, partner.

(Fern sighs) BUSTER: To watch more Arthur and play games with all the Elwood City friends, visit pbskids.org.

You can find Arthur books and lots of other books too at your local library.
