Paulette serves as Cinderella's fairy godmother, motivated by a solemn promise to her deceased best friend Frances to protect and guide Frances's daughter. This deep personal bond fuels her dedicated guardianship. She operates discreetly, often observing Cinderella from a distance while maintaining her cover as a village art teacher for local children. Her personality is consistently kind, gentle, and generous, always prioritizing Cinderella's well-being. Though possessing magical abilities as a witch, she exercises significant restraint, reserving her power for critical interventions during emergencies.

Her magical support manifests in diverse ways: granting Cinderella the ability to understand her animal companions Patch, Papy, Chuchu, and Bingo; transforming animals or objects like rocks into dogs to distract foes; shrinking Cinderella to retrieve lost items; summoning food; altering food flavors; extinguishing fires; and manipulating environmental elements such as rain or bridges to destroy threats or aid escapes.

A profound demonstration of her commitment occurs when she knowingly enters the Haunted Forest, where her magic is nullified, to help Cinderella retrieve a life-saving herb for the cruel stepmother. This act underscores her dedication to Cinderella's emotional needs above her own safety. Her role evolves from covert assistance to direct revelation. Initially concealing her magical identity and interventions, she ultimately reveals herself as the fairy godmother as the royal ball approaches. In this pivotal moment, she magically repairs Cinderella's mother's dress, creates a carriage, provides the iconic glass slippers (heirlooms from Cinderella's mother), and cautions about the midnight magic expiration.

Beyond practical aid, Paulette contributes to resolving supernatural threats, notably liberating the painter Zore from demonic possession by destroying his cursed portrait. Her awareness of Zore's tragic past informs her compassionate approach to his redemption.
