They play a significant role in Dragon Ball 's early comic relief and fan service, which is mostly exploitation of Bulma. In " The Secret of the Dragon Balls ", Goku tries to look to see if Bulma has a tail and moves her skirt up revealing her panties. Later on at Goku's house she tries to seduce him into giving her his Dragon Ball by showing him her panties and offering for him to touch them. He then lays on Bulma's lap and realizes she has no bulge. He takes her panties off to find out that girls have nothing there.
