The Rugrats Movie. Reptar was a main character in
Rugrats in Paris and had his own theme park called Euro Reptarland. There was a giant Reptar robot in Euro Reptarland which the babies piloted and fought against Jean Claude. Reptar has had his own ice show, which Lou believes is "sheer brilliance". The babies interrupted it, seeking a lizard they believe is a "Baby Reptar". •

gorilla and Reptar's enemy. In the episode "Toy Palace", Tommy and Chuckie activate a large robotic Thorg, who chases them through the store, repeating his catchphrase "Thorg hungry! Thorg want eat!" He is made to resemble

Captain Planet and the Planeteers,
