Rosita is a turquoise, Spanish-speaking monster who first appeared on Sesame Street in 1991 (Season 23). Hailing from Mexico, her full name is Rosita, la Monstrua de las Cuevas (Rosita, the Monster of the Caves). She is the second bilingual Muppet to ever appear on the show, speaking both English and Spanish. The first was Osvaldo the Grouch. She is good friends with Zoe, Elmo, Telly Monster and Abby Cadabby.
Rosita originally had wings attached to her arms, reflecting her original concept design as a fruit bat. In season 35, she was rebuilt and no longer had wings. In an interview, Rosita claims that her family flew from their cave (near Snuffy's) during a storm, like a flying squirrel, and she lost her wings.
Rosita has often presented the Spanish Word of the Day, and features frequently playing her guitar.
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 2007 resource video, Talk, Listen, Connect: Changes.
- In a 1999 episode, Rosita says that Prairie Dawn is her best friend, but in a 2000 episode, she looks for a best friend, eventually settling for Herry Monster. During the 1980s (and as listed in their profiles in The Sesame Street Treasury volumes 6 and 9), it was Herry and Prairie who were often paired as best friends.
- Years before Rosita first arrived, Big Bird revealed on his trip to New Mexico that he had made friends with a chicken named Rosita as well.
- Rosita is good with history, as well as geography.
