Petty Potts' most recent repto SWITCH spray doesn't seem to be working ... not that Josh and Danny were all that excited about being chameleons anyway - alligators would be way better! Plus, they're distracted by the mystery of who is sending them clues to find marbles filled with scientific code. But at school the next day, time seems to be going too fast for the twins, and when one of Danny's eyeballs rolls right round in its socket, they know things are getting weird. While Danny is distracted by the leafy coolness of his teacher's pot plant, Josh is causing a stir in PE, escaping the class bullies by climbing right up to the top of the gym ropes! How long will it be before the boys are boys again? And will they be able to find the next marble (and get their own back on those bullies) in the meantime?
