This dub features none of the voices established on Plaza Sésamo, except for Ernie. Big Bird is renamed "Abelardo" (not to be confused with Abelardo Montoya, his Mexican cousin and counterpart used on the show) and Grundgetta is voiced by a male voice actor. All of the musical numbers remain in English.
- Yamil Atala as Big Bird (Abelardo)
- Nancy MacKenzie as Miss Finch
- Herman López as Oscar the Grouch (Oscar el Gruñon)
- Jaime Vega as Enrique, La Rana René, and Papá Dodo
