After being displaced by a storm, Bugs Bunny finds himself in the castle of a mad scientist. The scientist, needing a brain for his robot, orders his orange, hairy monster, Rudolph, to capture Bugs. Bugs awakens under a mummy, panics, and flees. The frustrated scientist sends Rudolph to retrieve him, promising a reward. Bugs evades capture by impersonating a hairdresser and uses dynamite as curlers, leaving Rudolph bald.
Enraged, Rudolph chases Bugs to a chemical storage room. Bugs uses vanishing fluid to turn invisible and torments Rudolph, eventually shrinking him with reducing oil. The tiny Rudolph resigns and leaves through a mouse hole. Invisible Bugs celebrates, but the scientist makes him visible again, demanding his brain. Bugs refuses, and the scientist accidentally releases ether fumes, incapacitating them both. In a slow-motion chase, Bugs trips the scientist, who falls asleep.
Bugs, still in slow motion, prances away but trips and falls asleep in a stream that returns him to his flooded hole. Waking up, he thinks it was a nightmare until the miniature monster rows by, leaving Bugs bewildered.
