He is taken to his home and is introduced to his family who are all named after sweets: Eclair his wife and their nine kids: Cupcake, Pudding, Donuts, Jelly, Jam, Creampuff, Cocoa, Cookie, and Crepe). Their grandfather, Korinto, returns with his day's catch and a feast is prepared. As is the norm, no one believes how much Goku eats. The family tells him about Yaochun, the strongest man around.
Meanwhile, Tien Shinhan, Krillin, and Yamcha ask Master Roshi why he is not teaching them anymore. Roshi explains to them that he has nothing more to teach and that they should seek training on their own.
Korinto leads Goku to Yaochun and he asks him for a fight. It turns out that Yaochun is not the man Goku wants to meet, as he is beaten by Goku easily. Goku meets up with Korinto again who teaches Goku how to fish by feeling the river, sharpening his concentration skills. It would appear that this is the man that Goku was supposed to meet in the first place.
