The Penguins take Michelle to Planet “Cross Your Heart.” They find a little alien girl who promised to keep her finger in a dam that holds back an ocean of grape soda, but also promised her mother to clean her room before lunch. Michelle promises to take over for her. All is well and good until it seems the Alien Girl isn’t coming back, and Michelle needs to get going. Will they rescue the city from being flooded? Will they learn the value of keeping your word and not promising more than you can live up to?
