Abelardo is an orange and yellow, full-bodied Muppet crocodile who served as Big Bird's equivalent on Plaza Sésamo, the Mexican of Sesame Street. Abelardo made his debut in 1972 and, along with Paco, was active on the show until 1981. Two designs of both puppets were used, the first one from 1972 and the second design after 1978.
