Rugrats Go Wild is a 2003 American animated musical comedy crossover film based on the Nickelodeon animated television series Rugrats and The Wild Thornberrys. It is the third and final installment in the Rugrats film series as well as the second film in The Wild Thornberrys series. Christine Cavanaugh, the voice of Chuckie Finster, was replaced by Nancy Cartwright. The film was produced by Nickelodeon Movies and Klasky Csupo and released in theaters on June 13, 2003, by Paramount Pictures. It was the least successful film in the Rugrats series, grossing only $55.4 million worldwide and receiving mixed to negative reviews. The film used "Odorama," which allowed people to smell odors and aromas from the film using scratch and sniff cards (reminiscent of 1960s Smell-O-Vision).
