While playing ball with Grim and Cerbrous, Billy is told by Mandy to play somewhere else because she has to study for a big test tomorrow. Billy is soon convinced by his dad that in order to get a better grade on the than Mandy on the test, he would have to keep her up all night. Unfortunately, Grim was warned by Mandy that if she was to be interrupted while she sleeping or studying, she would do something terrible to Grim. So in order to keep alive, Grim manages to stop Billy's atempts to wake Mandy. Unfortunately, one of Billy's last pranks left Mandy flat on her face outside on the sidewalk. In the morning, it turns out it was Irwin who was sleeping in Mandy's room in a Mandy costume and Mandy slept outside in an abandoned dog house. Later at school, Mandy (as always) passes her test and Billy (as always) fails his test. However, Grim is punished (for reasons unknowned) and is now forced to listen to Irwin as he plays the saxaphone.
