Uncle Fester creates a new fabric called Happyester, so he and Gomez decide to present it to Norman Normanmeyer, who runs Normanwear. Normanmeyer is enthusiastic to buy the formula and offers Uncle Fester to be his partner. Meanwhile, a rival underwear company RumpCo has sent a spy, Underwear Hitman "Fingers", to steal the formula.
