The children's television franchise Gabby's Dollhouse has officially cast Celestina Harris in the role of Doozie, the little sister character that was first revealed in last year's film adaptation. Harris, known for her work in the television series Lioness, will voice the energetic, dog-loving younger sibling who contrasts with the protagonist Gabby's affinity for cats. The character announcement marks a significant expansion of the franchise's core cast and narrative possibilities.

Doozie will make her debut in Season 14, which launches on Netflix on September 14. The introduction of the sibling character is intended to explore new storytelling themes around family relationships and pet dynamics, with Harris describing the role during a recent podcast appearance as bringing creativity and upbeat energy to the series. According to the creators, the character will demonstrate themes of perseverance and problem-solving that align with the show's existing educational messaging for its young audience.
