Poppy, accompanied by her troublesome son Junior, his skunk friend, and Uncle Ereth the porcupine, responds to a summons to return to her ancestral home, Gray House, to save the mice there from destruction by a bulldozer.

The last thing Badger wants is a roommate, and certainly not Skunk, but since the house does not belong to him he does not have a choice; and soon everything in Badger's quiet and ordered life studying rocks is turned upside down (and where on earth did all the chickens come from)--but after he drives Skunk and his chickens away, Badger starts to miss his roommate and sets out to find him and make amends.
