As Gohan and Krillin head to Guru's place to awaken Gohan's hidden powers, they leave Bulma behind to look after the Dragon Ball. Frustrated at his loss of five of the Dragon Balls, Frieza begins firing powerful energy blasts all over the surface of Namek. These explosions cause the Dragon Ball to roll away from Bulma and into the water nearby. Bulma takes her submarine into the water to find the lost ball, but there she finds more than she bargained for. As she reaches for the ball, a giant crab thinks she is trying to steal her eggs, and begins to attack Bulma. Bulma saves the crab from a falling rock, and the crab gives her the Dragon Ball.
