It is the sequel to Tales of a Fourth Grade Nothing and Otherwise Known as Sheila the Great and is the third in the Fudge series.

Several months before they temporarily move from New York City to Princeton, New Jersey, she is born, named Tamara Roxanne, and called "The Baby" for weeks.

Peter's 4-year-old brother, Fudge, is extremely jealous of her, who earns the nickname "Tootsie" from their mother Anne's cute speak and their grandmother Muriel's favorite old song.

In the end, the Hatchers decide to move back to New York City, a decision punctuated by Tootsie's first word, "yuck", which she learns while undergoing a nappy change by Peter.

A Saturday morning television series based on Superfudge entitled Fudge ran for portions of two seasons on ABC in 1995.
