Radish is a type of vegetable Goku and Chi-Chi are seen growing in Dragon Ball: Yo! Son Goku and His Friends Return!! and Dragon Ball Super.
Goku and Chi-Chi began growing radishes in their garden after Kid Buu's defeat. When deciding who was going to battle Abo and Kado, the Z Fighters pulled radishes from the garden in order to see who got to fight, with the longest being the winner. Each participant pulled radishes very different from each other; for example, the radish Master Roshi pulled was shaped like the body of a female, which caused him to have a nose bleed. Trunks ended up pulling the longest and went on to fight the evil duo, soon joined by Goten.
During the closing sequence of the film, Abo and Kado join the Z Fighters and their friends at Mr. Satan's ruined banquet, where they are seen eating Goku and Chi-Chi's radishes.
- The name of Goku's brother, Raditz, is a pun on "radish".
