At Bimbo's Experimental Laboratory, Bimbo and Koko concoct a variety of compounds and elixirs. Their scientific experiments are interrupted when 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 Betty. Betty sprays the monster with flower spray, which turns him into a harmless dancing flower. Betty giggles and says, "You nutty dope fiend!"
