"Conga Counting Song'" is a filmed song sequence, seen on Sesame Street. Three kids run around town counting uno - dos - tres. Three more kids join them, making it seis. Finally, three kids join them with one smaller kid, for a total of diez kids. The song was also performed by Maria and the cast in a 2001 episode, where they counted monsters (Elmo, Telly, Lulu, Grover, Zoe, Herry, Rosita, Merry Monster and two AM Monsters) instead of kids. Rosita repeatedly sings the chorus of the song in a "Spanish Word of the Day" segment.
