A gerbil! He looked down at himself and realized that he had shrunk to roughly the size of the classroom pet, and that he was inside it's little cage in the corner of the room. Melissa also looked like a human-sized Gerbil, likely the one that used to be in the cage that Tim now inhabited. The cage was filled with a hamster wheel, a small house fit for a Gerbil, a small plate-shaped thing in the corner where the pets food would be placed, and a tiny plastic tube in the corner of the room that provided water. This was completely embarrassing for Tim, here we was, now the class pet, and completely naked, while the Gerbil that was supposed to be in the cage he was in, was living the life of a human! Tim had to get out of this life, and quickly, he didn't want to be stuck in the cage any longer.
He looked down at his wrist, to his relief the watch was still there, so he could swap with someone else and everything would at least be better than it was now! He tried to use the watch but Tim found that his body had the motor skills of an average Gerbil, which wasn't too useful when he had to try and use the one item that could guarantee his freedom. He kept fiddling with it when he heard one of the students speak up. "Ms. Mendez! Gabby has something in her cage!". Tim's heart dropped, he realized that one, he was a female Gerbil in the eyes of the world, and two, one of the students had seen him with the watch! And Ms. Mendez was walking towards him as he desperately tried to use the watch and switch before it was taken from him. He could be stuck in the life of a Gerbil forever if he didn't hurry!
