But what will she do when she finds out that Beast has squashed her egg-carton jewelry box? Meanwhile, Beast has a bigger problem. He and his best friend, Matthew Jackson, had to move the huge rabbit on wheels onto the stage for the spring assembly. When they started to push it, the monster rabbit ran amuck and rolled right off the stage. How will Beast and Matthew get the thing back together before Thursday's assembly?
