This is my chance to be a published author.

We have a problem.

That's great.

Maybe the problem can help Sydney think of an idea for her Commander Cressida story contest.

Now I'll have to figure it out myself.

So, where is that beach?

- Hmm, maybe it's a beach on Mars or Venus!

- But they don't have oceans there.

- Oh.

And that means no windsurfing?

- Now we have a problem!

- And that's a problem big enough for Commander Cressida, so let's solve it together!

Okay, first, do oceans exist on any other planets?

- I think they used to be on Mars and Venus, but they don't have oceans there anymore.

- Aha!

So we'll start there.

- What do you mean they're not there anymore?

How do you lose a whole ocean?

Oceans are really big, with lots of water.

- They are.

It's a mystery where the oceans on Venus and Mars went.

- I know!

Maybe someone was super thirsty and drank them all.

- Nah.

Even if someone could, they'd taste awful.

They are salt water.

- Huh.

Or maybe... someone took out the plug and the water drained out like a big bathtub.

- But those things can't really happen.

- You know what, anything can happen in my story.

It's up to my imagination.

What could the story be?

- What if Commander Cressida could make an ocean on Mars and Venus?

- Great idea, Mindy.

The question is, how will she carry all that water there to make an ocean?

- [squeaks] - Bucket by bucket?

That would take forever.

- Maybe she has a giant watering can!

[slow music] Eh, not enough water.

- What about a super long garden hose?

Whoa!

Hmm, I can't figure this out.

How can we get enough water to fill an ocean onto Mars or Venus?

- And carry enough water that far?

- [squeaking] [jaunty music] - What did you do that for?

- Oh, wait.

I get it.

Sunspot's showing us that if you make water really cold and freeze it, it turns into solid ice.

Then you can carry it more easily.

- Huh.

But how are you going to unfreeze it?

- [squeaks] - Ah, the old Bortronian heat lamp.

- Whoa, the ice melted into a puddle.

Now it's liquid water again.

- So, maybe the easiest way to carry a lot of water somewhere is to freeze the water into a giant ice cube.

A space cube.

- Uh, Earthies, where are we going to get a giant space ice cube?

- Um, Jet, there already are giant ice cubes in space, and they're called comets.

Remember my mom showed us a comet is basically a dirty snowball in space full of ice?

- [gasps] Right!

I remember now.

She called 'em dirty snowballs, or snowy dirtballs.

- So, if Commander Cressida can find a comet, she could melt the frozen water in there to make an ocean on Mars or Venus?

- Sounds like a plan, Sean-zo!

- Okay, let's all act out the story like a play.

I'll be Commander Cressida, of course.

Jet, you can be my helper, Captain Comet.

- Ooh, Captain Comet!

- And I'll be the intergalactic lifeguard.

I'm a great swimmer on any planet.

You can be Sirius.

Come on, I'll show you.

- [squeaks] [ice cube crackling] - Ooh, look.

- Where'd it go?

- Actually, we just saw what happened to it.

When water gets too hot, it boils and rises up as steam.

- That's right.

That must be what happened to the icy comet when we put it on Venus, because it was such a hot planet.

- What can we do now?

Venus was too hot for an ocean.

- We're going to find another comet to make another ocean.

But where?

- I know a place that's cooler.

Let's go to Mars.

It's still frozen.

- I didn't count on just how much cooler it is here on Mars.

- [squeaks] - So, if Venus is too hot and Mars is too cold, how can I make a great Commander Cressida story about an ocean on another planet?

I need to make it just right.

- That's it.

Just right!

Sunspot, remember the story I told you about Goldilocks and the three bears?

- [squeaking] - You know, the porridge?

- [squeaking] [soft music] - Once upon a time, there was a little girl named Goldilocks, 'cause she had gold hair.

And there were three bears, and they made three bowls of porridge.

- Porridge?

- That's a kind of hot cereal.

- So then the bears went for a walk, and then Goldilocks came into their house to taste their porridge.

She tried Papa Bear's and said, "Ouch!

This is too hot."

And then she tried Mama Bear's and said, "Yuck, this is too cold."

So see, one bowl's too hot and one bowl's too cold.

But one bowl was just right.

[dynamic music] - So, what I get from that story is... - Wanting to eat lots of porridge?

- No, that Venus is too hot, like Papa Bear's porridge.

Mars is too cold, like Mama Bear's porridge.

But Earth is like a Goldilocks planet.

It's just right.

- So if Commander Cressida can make one of these planets just right, we can put an ocean there.

- Ha-ha!

I've got a great idea.

Sunspot, we're gonna need your Bortronian heat lamp for the story.
