A bald monk named Kuririn makes his way to Kame-Sen'nin's island, and he demands training too. With him, Goku rescues a thief named Lunch to take her to Kame-Sen'nin's house, so that he agrees to start the training. Kame-Sen'nin gives them strange methods to train such as running through jungles, finding rocks or delivering milk all across the island. Kame-Sen'nin continually makes the training harder by having the two wear a 2-ton turtle shell. After finishing their training, Kame-Sen'nin takes them to the Tenka'ichi Budōkai, which is a fighting tournament that reunites the strongest warriors from the planet. Goku and Kuririn easily win their first fights and manage to enter the finals. Kuririn fights against Bacterian (バクテリアン, Bakuterian), a fat man who uses disgusting tactics to fight, such as his strong smell and flatulence, but Kuririn manages to defeat him by his own methods.
