Ten year old Timmy convinces his parents that he’s capable of staying home alone, but his babysitter, Vicky, isn’t happy now that she’s out a night’s pay. Determined to see who’s stealing her gig, Vicky snoops on Timmy and finds him having a great time with his odd Fairy Godparents. Mr. Beasley shares from the forgotten toy box the story of Stanley, a grownup who behaves like an infant until he is cursed by a talking doll that tells him he will soon be in diapers--and that’s what happens: Stanley turns into a "big" baby. Getting larger and larger, Stan terrorizes the city in King Kong-like fashion. He’s only stopped when helicopters play lullaby music, shrinking him as he falls to his bed. Once again, Jelly plays tour guide to one of her slightly unusual relatives. This time it’s Uncle Betty, who seems to have a problem finding that "special someone." On a trip to the museum, Uncle Betty finds the love of his life in a really interesting houseplant.
