Illus. in full color. "While Granny is a-rockin' and a-knittin' and Ma's a-cookin' and Pa's a-fixin', that old possum in his top hat and vest just keeps on knocking. The narrator, a redheaded boy, tries to tell family members about the possum, and when the family checks, the possum hides. Should be popular with story-hour groups."--Booklist.
