After three weeks, Goku finally catches Bubbles and completes his second challenge by striking Gregory, the flying grasshopper, with a large mallet. This success allows him to fully master the planet's gravity. King Kai then teaches Goku his signature technique, the Kaio-ken. Meanwhile, on Earth, Gohan concludes his training with Piccolo. The remaining Z Fighters finish their training with Kami and subsequently go their separate ways.
