On a stormy night, Donald and his nephews overhear the radio announcer, Breckenridge, notify the listeners that a mountain gorilla named Ajax (Disney) has escaped from the city zoo. The nephews pale with fright, and Donald laughs at them. As a prank, Donald frightens his nephews with gorilla hands to make it seem as if he is Ajax. The nephews spotted Donald from the keyhole and in order to retaliate on their uncle, the nephews dress up in a gorilla suit and lay under Donald on the armchair (which Donald was sitting on to read a book), and eat Donald's lollipop while Donald is unaware of them. Donald heard the crunchy noise and discovers the sharp teeth and stare up at the fake gorilla, pale with great fright, he runs away. The nephews popped up from the suit and all laugh hysterically.
