Mona the mouse has finally found a place to call home, the cozy Heartwood Hotel, where she works as a maid and sleeps snuggled up in a room with her best friend. Following the festive St. Slumber celebration, most of the guests have settled in to hibernate, and the staff is looking forward to a relaxing winter. But disruptions abound, from a difficult duchess to a mysterious midnight snacker. As the snow stacks higher, Mona will have to gather friends...

Spring is here and the animal staff at the Heartwood Hotel are busy arranging a series of festivals and competitions to drum up business and to show its patrons that Heartwood is the greatest hotel in Fernwood Forest.
