Summary

After switching bodies with Goku, Ginyu and Jeice return to the Dragon Balls only to find them already dug up. Krillin and Gohan mistake him for the real Goku but soon discover the truth. Goku appears in Ginyu's body and explains the whole ordeal. He reveals that Ginyu's mind must be connected with his body to unlock its full power. Goku's body at full power was 180,000 yet Ginyu could only get 23,000 out of it much to his shock. Krillin and Gohan take him on and knock him around with ease.
