In celebration of Hispanic Heritage Month, bachata singing sensation Romeo Santos joins Elmo on the set of Sesame Street to sing "Quiero Ser Tu Amigo (I Want to Be Your Friend)." Watch Elmo learn a few Spanish words and make new friends.

Lesson: When you see somebody you'd like to get to know, why not just walk up to them with an hola or hello? Or you could just say quiero ser tu amigo. That means, I want to be your friend. Try it out on the playground today!
