Gokiburi Game

All the kids start out as cockroaches (gokiburi).  The do an action to show that is what they are.  They find another cockroach and do rock, scissors, paper and a set dialogue.  The winner then becomes a snake.  Only snakes can talk to snakes and only cockroaches can talk to cockroaches.  The snakes then become mice when they win, then birds, then rabbits, then tigers (any animals the kids know is ok as long as it becomes bigger).  In the end they become human and do rock, scissors, paper with the teacher.  You may need to become a cockroach from time to time to help out the kids that are bad at rock, scissors, paper.
