A 1999 direct-to-video release, Animaniacs: Wakko's Wish is also Yakko, Wakko, and Dot's final adventure, but the movie is tonally different from the show thanks to the trio's story playing out against a 19th-century setting. In the movie, Wakko makes a wish on a star to save his sister, Dot, but things get chaotic when other wishers get in on the action.
