Sophie Mouse wants to prove how wonderful mice are for a school project she is doing with her brother, Winston, but starts to have doubts when, even with Hattie and Owen's help, she is unable to learn to swim.

While camping, Sophie, Hattie, and Owen hear strange noises in the woods and decide to investigate.

Sophie and her friends find a great big paw print near Forget-Me-Not Lake. They follow a trail into town, where they learn that food has gone missing from Mrs. Mouse's bakery and part of the library has been destroyed! What kind of animal could be making these huge paw prints?

"Sophie meets a ladybug setting up for a surprise party in Silverlake Forest. Sophie offers to run some errands in town to help her new friend. But by the time Sophie gets to town, she's forgotten what the ladybug said! Will Sophie's friends be able to help her in time to pull off the big surprise?"--

With the help of Hattie Frog and Owen Snake, Sophie Mouse puts together the first Silverlake Art Show but when the big night comes, she finds she is not the star of the show.

"Sophie Mouse has never lost a tooth before. But it looks like that's about to change because Sophie's tooth sure is wiggly! She's a little scared until a friend tells her that when you lose your tooth and put it under your pillow, the tooth fairy brings you a present! Now Sophie can't wait for her tooth to fall out. Then, Sophie does exactly what she's supposed to but the tooth fairy never comes! What did Sophie do wrong? Or is the tooth fairy simply...

As a school assignment, all the students at Silverlake Elementary are building boats, but Sophie worries that they will not be able to use the boats when there is no rain to fill the pond.

Sophie the mouse, Hattie the frog, and Owen the snake find a charming and apparently abandoned cottage hidden in the woods, and soon start spending all their free time there, cleaning and fixing it up for Mrs. Rabbit's family who are in need of a home--the project is going find until the owner shows up.
