Los Dinosaurios is the Spanish-language version of Dinosaurs, broadcast in Mexico. Like most dubs of American imports, only the dialogue was changed, with an announcer translating on-screen titles and logos. However, the Spanish package did include "I'm the Baby (Gotta Love Me)" and a second Baby Sinclair music video (edited from show footage) with most broadcasts.
