Cousin Itt returns from the South Seas to a welcome home party, but it soon looks as if he's losing his hair (and in bunches, too). Before there's nothing left of him, Uncle Fester orders a new chemistry set to brew up a batch of hair tonic. It's a success, and soon there's hair growing everywhere - on portraits, doorknobs, Thing's box, but most importantly on Cousin Itt (sporting a new bristle to top his floor-length tresses). He's saved, while Fester, himself, becomes a new man, ready to court the ladies with a full new head of blonde wavy locks. Unfortunately it's only temporary, but fortunately Cousin Itt's problem isn't Cousin Itt's problem after all.
