Fred invented a fat-reducing drink. That is, he thinks he did, but after he drinks it, he shrinks and ends up being about a foot high.
Fred is "on an inventor kick" again, this time attempting to perfect a revolutionary weight-reducing formula. When he samples some of the compound (Fred-O-Cal) that he has mixed and stands on a weight-scale, he is pleased to note a modest loss of pounds and decides to drink a larger dose, which diminishes him not horizontally but vertically, to a finger-sized Flintstone who frightens Dino, amuses Pebbles, and shocks Wilma, who must resign herself to the fact of her husband's "little problem".
Fred has a big enough mouth to eat and brush his teeth, and he bathes in the kitchen sink and sleeps in Pebbles' doll crib. Fred expects that his chemical concoction will "wear off" eventually, but in the meantime, he is tempted to appear on The Ed Sullystone Show as a "dummy puppet" with Barney as his "puppeteer". Tiny Fred speaks while Barney drinks water and walks of his own volition away from Barney, who impresses Sullystone with his apparent ability to imperceptibly throw voice and move his "puppet" without use of hand or wire.
However, in the middle of their "puppet" act on live, national television, Fred, seated on Barney's knee, grows back to normal, collapsing the chair on which Barney is seated- and Fred and Barney are violently expelled from the Ed Sullystone studio. Fred vows never again to experiment with chemicals and pours his Fred-O-Cal out of a window and accidentally into Dino's water bowl, with the result that Fred's pet (now wearing lenses because the sight of a diminutive master caused him to question his vision) becomes a miniature dinosaur.
