The Multimonstruo is the Plaza Sesamo equivalent of the Sesame Street Monsters. Unlike the latter, however, there is actually only one monster puppet, a red orange creation who is recycled endlessly in different guises, most of which do not have names. However, some of his more frequently adopted personalities include a pirate, baby, auto racer, magician, or musician.
Some of the identities are as follows:
- Cuernos
- Carlo de Villamelone
- a tourist (that speaks only in monster babbles)
- a baby
- a pirate
- a photographer
- an actor
- an actress
