Plot

Jaq and Gus create a storybook based on three events that happened after the first film. The stories include Cinderella's opposition to the court's strict etiquette, Jaq's becoming human for a day, and Anastasia's redemption through love.

The movie explores Cinderella's "happily ever after" life as a princess in three stories, with help from her Fairy Godmother. First, Cinderella's awkward first days at the palace, during which she tries so hard to fit in that she forgets to be herself. Second, how Jaq feels so left out that he wished to be a human. Third, how Cinderella teaches one of her nasty stepsisters how to smile, which leads to her own true love.—Britney

Prologue In the royal palace, Cinderella's mice friends Gus and Jaq head to a chamber where the Fairy Godmother is reading the story of Cinderella to the other mice. Much to their disappointment, Gus and Jaq arrive just as she has finished the story. With her help, the mice set off to make a new book to narrate what happens after the Happily Ever After, by stringing three segments of stories together into one narrative.

Aim to Please In the first segment, Cinderella and Prince Charming return from their Honeymoon, and Cinderella reunites with her mice friends and her dog Bruno. She is later put in charge of the palace banquets and parties while the King and Prince Charming are away. However, Cinderella is dissatisfied with the emphasis on tradition, and decides to organize the upcoming party her own way. Although he initially seems to be shocked at Cinderella's changes, the King ends up satisfied with the party.

Tall Tail In the second segment, Jaq thinks he is too small to help Cinderella in the palace as he did in the first movie. The Fairy Godmother turns him into a human, named "Sir Hugh," so he can help out. However, this does not stop Pom Pom, the palace's cat, from chasing Jaq around. After an incident with an elephant at a fair, he learns to be happy with himself.

An Uncommon Romance In the last segment, Anastasia, one of Cinderella's stepsisters, falls in love with a baker named Lathyn, of whom her mother Lady Tremaine and older sister Drizella disapprove. Cinderella, unbeknownst to anyone else, arrives and secretly watches as Lady Tremaine berates Anastasia, thus leading her to help Anastasia in getting ready for the ball together. Later at the ball, Anastasia thanks Cinderella for helping her. Lucifer also has an encounter with Pom Pom, the castle's cat, with whom he falls in love and enlists the help of Jaq & Gus to woo her. They reluctantly agree, but with the understanding that Lucifer won't chase them anymore.

Epilogue The mice finish their book, and the movie ends as they gather in front of the fire with Cinderella, who begins to read their story.
