Fergus and Zeke love being the class pets in Miss Maxwell's classroom. From science experiments to art projects, they do everything the students do. But on Field Day, none of the events are the right size for the small mice -- the limbo is too easy, the high jump is too hard, and kickball is absolutely terrifying! So Fergus and Zeke create their own Field Day Challenge, with mouse-size tug-of-war, acorn throwing, and Hula-Hooping. After all the fun and exercise, it's time to go back to the classroom -- but Fergus and Zeke are locked out! Will they be able to use their new skills to get inside in time for ice pops?
