Goku, still asleep, falls into the very heart of Hell, where he awakens on impact. He finds a well-tended tree growing there (not to mention the Hell Tourist Board and Hell Park), and unaware that it is the exclusive property of King Yama, tries to snack on its fruit. He is KO'ed before he can touch any by Gozu and Mezu, two heavily-muscled guardian demons, and strikes a bargain with them: If he can outperform them at one game of their choice each, they'll put him back on the Serpentine Road.

     Goku manages to beat Gozu at a sumo match, and defeats Mezu in a game of tag that ranges all over Hell. Good to their word, they try to put him back on the Road using a seesaw, but Goku keeps smacking his head on the invisible one-way barrier between Heaven and Hell. Lacking any other way to keep their side of the deal, they show him the secret route back to the Serpentine Road — but it lets out inside King Yama's desk drawer! Now Goku has to travel the entire length of the Serpentine Road from the beginning again!
