Sophie Mouse likes being a mouse. So she's excited that she and her classmates are making presentations for school about life as the type of animal they are. Sophie has already made a list of things she can do--run fast, scurry into small places, and more. But while playing at Forget-Me-Not Lake with her friends Hattie Frog and Owen Snake, Sophie realizes one thing she definitely can't do: swim! Hattie and Owen are having so much fun in the water, and Sophie will never be able to join them. Sophie starts to think that being a mouse isn't so special, after all. When Sophie's friends notice her disappointment, can they figure out a way to get her out on the water? Sophie Mouse wants to prove how wonderful mice are for a school project she is doing with her brother, Winston, but she starts to have doubts when, even with Hattie's and Owen's help, she is unable to learn to swim.
