Granny gets cheated out of yet another life savings by the dastardly Blockheads, who trick her into thinking they've made her younger by spray painting her hair and removing the lenses from her glasses so she can't see her wrinkles. There's some more "hilarious" blind Granny driving, and Granny visits her loving family, only to find out she's been cheated. However, she's in luck; it seems Professor Kapp has discovered the fountain of youth (or, more precisely, the flashing light thingy of youth) and he offers to make her 37 years old again. Minga, the meddling little girl that she is, reprograms the machine to make her 7 years old. Kapp refuses to notice the new computer display and next thing we know, Granny's a little girl. To complicate matters, the Blockheads steal the machine so they can use it at their youthful boutique. Gumby realizes something is amiss when people walk into the boutique and come out 7 years old (seems they didn't know how to reprogram it), and a stop is put to them. Granny decides that being old and withered and frail is the life for her and returns to her normal age.
