Rosita is a turquoise, bilingual monster who first appeared on Sesame Street in 1991 in Episode 2888 (Season 23). Hailing from Mexico, her full name is Rosita, la Monstrua de las Cuevas (Rosita, the Monster of the Caves). She is five years old, and celebrates her birthday on December 7. She is the second bilingual Muppet to recur on the show (after Osvaldo the Grouch), speaking both English and Spanish.
Rosita has often presented the Spanish Word of the Day, and features frequently playing her guitar, which Luis taught her to do in Episode 3794. She's very good with history, as well as geography.
Rosita has an extended family which includes an abuela and other relatives. Her dad, Ricardo, served in the military and is in a wheelchair due to injuries related to his service. He made his debut with Rosita's mom, Rosa, in the 2008 resource video, Talk, Listen, Connect: Changes
