The Strangest Robot

After waking up from his transformation, Gohan finds his tail gone and a new set of clothes that resemble his father's gi. But he has no time to figure out what happened, as hungry animals descend upon him. Gohan escapes, but falls into a cave where he finds an ancient Capsule Corp. robot that's been trapped for over thirty years, and it's not too pleased about having company. Wanting to escape the cave, he asks the robot for help, but it's not interested. However, the robot lets out his soft side and helps Gohan get some mushrooms to eat. Later when Gohan tries to help the robot escape, the cave starts collapsing and the robot helps him, throwing him to safety.
