Learn to be art smart with your friend Elmo and these two artsy Sesame Street episodes. When Zoe's pet rock, Rocco, needs a friend, Elmo uses arts and crafts to build a new friend out of ordinary things on Sesame Street. Do you know what a collage is? It's a bunch of things put together to make a picture, and Elmo's going to make one with the help of his Sesame Street friends. Both of these stories are followed by the rest of their full hour episodes filled with additional art films and favorite segments like Elmo the Musical and Elmo's World.
