Mmm!

[slurps] [munching] - Uh, Dad?

- Mmm!

That's good!

Uh, you--you want to try?

- Mr.

Propulsion, why are you standing on your head?

- Uh, just baking some pineapple upside-down cake.

The recipe looked easy, but I'm not sure how long I can stay like this.

- Well, we have a science question.

We were wondering why Pluto used to be a planet but now it isn't anymore.

- [grunting] Ah, dear little Pluto.

Yeah, by vote in the scientific world, it's now considered a dwarf planet.

- A dwarf planet?

So it's still a planet?

- Nope, not at all.

A dwarf planet is not a planet, just an object in space.

- But why did the scientists decide that it's not a planet?

- Well, for one thing, it's small.

It's smaller than the other planets.

- But, Mr. Jet's Dad, I'm smaller than the other kids, and I'm still one of the group, right?

- Yeah, we wouldn't vote you out of being one of the kids.

- And maybe Pluto's small now, but when it grows up, it could get bigger.

- Huh, well, uh, technically-- I mean, that is, uh-- [bell dings] Oh, ha-ha!

There's the oven timer!

[chuckles] Thank goodness.

Now, who wants cake?

- Mr.

Propulsion, we're gonna go to the DSA and get some answers from Dr. Rafferty.

- You mean your mom?

- Yes, but Dr. Rafferty sounded more professional.

Could you please save us a piece of cake?

- [chuckles] Will do.

- Yeah, maybe we can get those scientists to take Pluto back into the planet club again.

- You can do it!

I know you can!

- We'll let you know what we find out, Mindy.

- Thanks.

Come on, Sunspot, let's build a Pluto planet for show-and-tell.
