As Bulma\'s father and his crew work on Kami\'s spaceship, Bulma telephones Krillin telling him about the spaceship. Krillin immediately relays the news to Goku, Gohan, and Chi-Chi. Chi-Chi suddenly leaves for no apparent reason, and Gohan sees this as his chance to train, since Goku and Krillin were sleeping. When Chi-Chi comes back, she finds him gone and is furious with Goku and Krillin for letting him leave. Gohan is actually training doing vertical pull-ups on the hospital walls. Next he practices balance by walking on the rails. He hears his mother coming, and when she finds him, he is reading. His excuse is that he wanted to enjoy the nice weather.
