Synopsis: Vegeta and Nappa, now on Earth, use their scouters to find the two strongest ki on the planet- Piccolo and Gohan. Kururin joins them just as the Saiyans find them. Nappa plants strange creatures called Saibamen. Tenshinhan, Chouzu, and Yamcha arrive, and they decide to each go one-on-one with the six creatures. Tenshinhan easily defeats his opponent, which Vegeta finishes off to motivate the others. Yamcha seemingly defeats his, but it recovers and grabs onto him, self-destructing. The blast kills Yamcha, angering Kururin, who prepares an attack of his own.
