Goku. He'll kill him with one kamehameha. Obliterated. Then he'll call Krillin, Vegeta, Yamcha, Bulma, Roshi, Gohan and Chi Chi to come eat all the spinach with him. Then he'll all be like no wtf, except for Vegeta and Gohan. Bulma comes along too with Vegeta, and Oolong, Puar and Yamcha were at her house. Gohan also stops by to see Piccolo and Piccolo accepts his invitation to come along. Piccolo is intrigued to see the plant version of himself. They all go around and watch the spinach being eaten.
