Candy (あめだま, Amedama) refers to any kind of artificial sweet food and is a common food in the universe. It is most notably used in the series when Majin Buu was on his rampage, turning many Humans into candy. The Ginyu Force often talked about candy, making bets in order to get some.
After being turned into a coffee-flavored jawbreaker by Super Buu so that he can be consumed, Vegito is still able to fight as the small jawbreaker candy. Not only does Vegito retain all of his power, but he is also extremely fast, and far too small for Super Buu to hit; thus using an original attack to shoot in Super Buu's mouth and out the back of his throat, unscathed. In the dub, he calls it his "Pinball Attack". However, while this small size gives him a colossal advantage in battle, he is not invulnerable and is unable to use any of his special/ki attacks.
