Castles in the Marsh The Muskrat - capable swimmer, adequate if somewhat wobbly walker, and our largest mouse - faces danger wherever it goes and whatever it does. One predator threatens it like no other. a mammal with silken fur that matches the way it moves over land and through water with silken ease, it brings danger to the very door of the Muskrat's water-bound lodge. No registration is required. Please come at least 45 minutes early as seating is limited (due to City Fire Code) and on a first-come first-serve basis.
