The Challengers again try to take a peek at their possible future children. They see instead Skokie Johnson, a crook they just arrested, 25 years in the future. Skokie learned a "fountain of youth" formula and, still young, vows to take his revenge on the Challengers' kids, sending them a booby-trapped package. Skokie digs up a time capsule and releases a huge "phantom" that wreaks havoc. The Challenger Kids helicopter to battle the Phantom and try to disperse it with a wind tunnel fan. Their dads arrive just in time to blow the Phantom to shreds and Skokie reverts to old age and is arrested.; The Challengers surround the lab of "Wizard" Welles who has built an electronic brain to transfer its infinite knowledge into his own brain. Rocky drops through a skylight and gets his brain zapped to giant size, making him a genius. When Wizard freezes citizens solid with red snow, Rocky concocts a gadget and super-melts it. When Wizard uses a force field and bell-jar vehicle to steal chemicals, Rocky tosses radioactive dust to track it. Finally Rocky matches wits to out-think the electric brain, and it blows up from overload. Rocky's back to normal, as Red quips, "beautiful but dumb!"
