I think that’s actually what it was, then got made into a joke. I also forgot about the reverse werewolf, wolfman or whatever. He wanted to kill Jackie Chun(Master Roshi in disguise)because he blew up the moon(yes, same moon Picollo later blew up again. Kami put it back together after getting rid of Goku’s tail). His real reason?

He’s a wolfman who turns human during the full moon, and now he cant get a girlfriend. So they use Krillin’s bald head to fake being the moon and he transforms… Into a human uglier than his wolf form. He’s happy but Krillin comments he probably had a better chance as a wolfman.
