A dinosaur friend of Goten's is kidnapped and taken to the circus. Gohan, as Saiyaman, decides to take him back to his parents before they go on a rampage in the city, but is stopped by Videl, who thinks he's stealing the baby dinosaur. When the dinosaur parents arrive, everyone finds out that Saiyaman was right, and after a brief skirmish, the parents are able to fly away safely with their baby. Unfortunately for Gohan, Videl found out that he is the Great Saiyaman. She says that she will divulge his secret to the press unless he enters the World Martial Arts Tournament, and teaches her to fly.
