Tom suspects Feeny is up to something when Feeny's Ivory Tower is all lit up after 8:00 at night. Feeny's foolish fog is intended to make everyone foolish and him the smartest person ever. The ingredients for his fog include a toothless comb for bald-headed men, rubber chewing gum, and hot ice cream. The fog causes Manfred to act like a silly bird, it makes a man and his baby change places, a mom act childish, a teacher act like a dunce, and two zoo lions dance. Tom turns the tide om Feeny's fog by changing into an electric fan.
