The Hatcher family temporarily moves from New York City to Princeton. Fudge is extremely jealous of his new baby sister Tamara, who earns the nickname "Tootsie" from her mother's cute-speak and Grandma's favorite old song. Peter deals with the fallout from Fudge's various problems, which include a spat with the kindergarten teacher who refuses to use the name "Fudge", antics trying to get rid of the new baby, and Fudge's constant desire to involve himself in Peter's activities, especially with Peter's new friend Alex. In the end, the family decides to move back to New York, a decision punctuated by Tootsie's first word which she learns while undergoing a diaper change.
