Pablo Bigotasso is a Multimuppet artist who appears occasionally on Plaza Sésamo. He often uses his art to demonstrate geometric concepts, and has also been known to innocently create his masterpieces on public walls.

Bigotasso features prominently in the video release Me Gusta Ser Yo, in which Pancho, Lola, and a neighborhood kid tour his gallery. In more recent appearances, a large yellow moustache has been added to the character.

Bigotasso is a parody of the famed painter Pablo Picasso.
