Barbie: Mermaidia or Barbie Fairytopia: Mermaidia is a 2006 direct-to-video computer-animated film directed by Walter P. Martishius and William Lau, and produced by Mainframe Entertainment. It is the 7th entry in the Barbie film series, a direct sequel to Barbie: Fairytopia and the 2nd film in the Barbie: Fairytopia series. The film stars Kelly Sheridan as the voice of Elina and Chiara Zanni as the voice of Nori. The plot follows shortly after the events of the previous sequel, focusing on a now-full-fledged fairy named Elina and a mermaid named Nori who attempt to rescue Nalu, a merman prince, from the clutches of the evil Laverna. Like the previous CGI Barbie films, a line of dolls and toys were produced and released with the film. This was also the last Barbie film to be released on VHS.
