A prankster sets out to sabotage a teacher's trap at the "Happy Easter School." The teacher had planned to use a cake as a trap for the prankster and other children. The prankster discovers the cake is in a safe in the teacher's office, which is protected by a bomb. After defusing the bomb, the prankster switches the cake with a regular one and then adds a special icing that makes the cake have a surprising effect. When the teacher eats the cake, it somehow causes her to be lifted into the air and "hit" by a plane, completing the prankster's goal.
