When Bruce gets home from a southern migration trip with his goslings, he is tired. He is grumpy. And he is definitely not in the mood to share his home with the trio of mice who have turned his den into a hotel.

There's a possum pillow fight wreaking havoc in one room, a fox luring guests into a stew in the kitchen, and a snuggly crew of critters hogging the bed. Bruce growls and grumbles and tries to throw them all out, but the entrepreneurial mice just can't take a hint. Bruce is in a little over his head, especially once the goslings join the staff. Will this grumpy bear ever get his quiet, peaceful den back to himself?
