Milly and Molly save a tadpole. But as the tadpole grows, the problem of where to keep the amphibian becomes more difficult. There is only one place the girls can find which is suitable: the school playground. Unfortunately, this location is used by the soccer team and a frog’s habitat isn’t compatible with stomping football boots. Milly and Molly have to put on their problem-solving hats so the frog can live happily ever after.
