At Bimbo's Experimental Laboratory, Bimbo and Koko concoct a variety of compounds and elixirs, including a drink that is so hot it turns a black cat into a dragon head, as well as turning the cat into a white and black striped one. Their scientific experiments are interrupted when, through a huge drop of the chemical, they see a bathing-suit-clad Betty taking a shower on the roof of her penthouse. Distracted by Betty as she sings "Penthouse Serenade," the two fail to realize the chemicals they've mixed are still on the boil, one of which turns into a Frankenstein-style monster. The creature sees Betty, and crosses over the phone wire to menace her. Although Bimbo and Koko make an effort to stop it from reaching her, the monster defies gravity and reaches the penthouse. Once Betty realizes it's right behind her, she sprays the monster with flower spray, which turns him into a harmless dancing flower. Betty giggles and says, "You nutsy dopesy!"
