Sean, what are you doing?

- According to the "Big Book," rainbows are really made of light.

Sunlight gets broken up into lots of different colors by tiny droplets of water.

- Okay, but if the colors come from sunlight, maybe we don't need a flashlight.

We've got the Sun right here in the sky.

[soft piano music] - Hey, yeah.

Now we just need to somehow add water.

[water patters] ♪ ♪ both: [gasp] The sprinkler!

♪ ♪ both: Hmm... - Okay, we last saw the rainbow going in this direction.

Come on.

[slow, stealthy music] Hmm... ♪ ♪ - Jet, do you see it?

- Hmm, I think the rainbow is hiding right behind these bushes.

And that means... - Also a little green... - Wish granting... both: Leprechaun!

[shushes] One, two, three... grab him!

- Ooh!

Ooh!

- Oh--oh--whoa!

I got it!

Oh!

- [squeaks] - Whoa... - [chattering] [both gasp] [Riverdance music] - Wow, I found the famous green leprechaun, who, for some reason, is tap-dancing!

Oh, Mr. Leprechaun, I'm so excited.

Now you grant me my one fondest wish.

Ah, St. Patrick's Day.

What a great Earthie holiday.

- [squeaking] - Okay... what should I wish for?

Hmm... Every marshmallow in the world?

No.

Oh!

A big swimming pool full of marshmallows?

- [squeaking] - [groans] I can't decide.

There are too many great things to wish for.

[sighs] I wish Sunspot was here.

He could help me decide.

- [squeaks] - [gasps] Sunspot?

Great to see you.

Wait, you mean you aren't a leprechaun?

- [giggles] Jet, you silly.

That's Sunspot.

- [gasps] I got my wish!

I wished that Sunspot was here, and the leprechaun turned into him.

Ha!

What a great magical Earthie holiday!

♪ Ha dih-dah-dah dih-dah-la dah-doo ah-ha-ha... ♪ Uh, hey, Sunspot, you're covered in green paint.

We need to give you a bath.

- [anxious barking] - Hey--[grunts]--come on, boy.

Back in the saucer.

Don't worry, Sunspot.

I'll think of a way to make it a fun bath this time.

You'll love it, I promise.

♪ ♪ [jet engines whooshing] - Jet, Mindy, you're just in time.

- We found a way to make a rainbow right in the backyard.

- You did?

- See?

The water from the sprinkler looks like a rainbow when the Sun shines through it.

- See, Sunspot?

I told you I'd come up with a fun way to wash the paint off.

It's not a bath.

It's a rainbow dance!

- [squeaking ecstatically] [squeaks] [all cheer] - So fun!

- Yeah!

- This is awesome.
