From Muppet Wiki

Ana was a character from Barrio Sésamo, the Spanish version of Sesame Street.

She was an adult human character who appeared in the second period of the series, from 1983 to 1987. She interacted with human-size Muppets Espinete and Don Pimpón.

Ana was a student with a mole on her face. She lived in a flat which was directly over Espinete's home (although Espinete was seen using different places as a home).

Ana had a know-it-all attitude similar to Don Pimpón's.

She was also popular because of a catchy song she sang, Soy Ana ("I'm Ana").
