Ash and friends stop at a Hot Spring to relax for the day. While playing a game, Chikorita, Cyndaquil and Totodile become angry with each other. When the ball they are playing with rolls away, the three of them give chase, but eventually become lost inside of a cave with Meowth. Now they must work together if they are to get back to their trainer. Meanwhile, Jessie and James are beginning to think of a new scheme to capture the starter pokemon.
