Goku (you): Bulma, what is that machine?

Bulma: Oh this? Baby Ray! Turns somebody into their baby selves! They keep their memories and power though.

Goku: Cool! Where will you test it?

Bulma: You take it and use it on Mr. Dog. He will become a puppy again. He will be able to be immortal!

You use the ray on Mr. Dog (Bulma’s dog) and he becomes a puppy!

Goku: Amazing! Can I take it PLEASE???

Bulma: Ugh, fine.

At home, Goten gets hands on it and zaps you! You are a baby now!
