Miss Small, the gym teacher, is teaching A.J., Andrea, and the gang to juggle scarves, balance feathers, and do the Chicken Dance! Is this any way to stay in shape? Whatever happened to good old dodgeball? In fact, all the grown-ups at A.J.'s school seem to have something wrong with them. What's going on here? What are A.J. and the kids in his class going to do? They've got to convince Miss Small to act her age before the end of the year! Never before has school been this mixed up -- or this much fun.
