Battle of the Dum-diddys

Hey! Where Is Everyone? That's what Bernie Bridges wants to know when he can't find any of his friends. Everyone has disappeared! And when he finally does find them, they're acting really weird. For instance, his shy friend Chipmunk thinks he is a fearless warrior, and football star Jennifer Ecch thinks she is a princess. What is going on? Soon Bernie realizes that everyone at Rotten School is acting! They are all playing parts in a big battle. A battle between the Dum Diddys and the Knighty Knight Knights. But it's not a real fight. It's a video game called Wungo Warriors-and everyone has to pay that spoiled rich kid Sherman Oaks to play. Bernie can't let Sherman get away with this. He has a plan to outsmart Sherman-by bringing the Wungo Warriors to life! What Bernie doesn't know, though, is that a real-life battle between the Dum Diddys and the Knighty Knight Knights could shut down Rotten School forever.
