Elmo and Zoe have an arts and crafts play date, but Rocco, Zoe's pet rock, is upset that he doesn't have his own play date. Elmo volunteers to find a friend who is round for Rocco and brings in a balloon. But Rocco wants a friend with a face and hair. Alan overhears the problem and suggests using arts and crafts to make Rocco a friend. Together, Elmo and Zoe use stickers and cotton to make a face and hair on the balloon. Rocco tries to play with Balloon-o, but Balloon-o floats away. Alan sees what happened and explains that Balloon-o floated away because he was filled with helium, which is lighter than air. Elmo tries to find Rocco a friend made of something that is heavier than a balloon and is round, so he returns with an egg. An egg is an oval but it will do. Zoe and Elmo draw a face on the egg with crayon and give it boots and a hat. Rocco begins playing pat-a-cake with Eggy, but Eggy accidentally breaks. Alan explains that Eggy broke because egg shells are very fragile. Elmo now needs to find a friend who is not too light or too fragile and is round. He notices Alan grabbing for a round sponge and thinks that the sponge could be the perfect play date friend for Rocco. Elmo explains that a sponge isn't lighter than air so it won't float away, and it's not fragile so it won't crack. Together, Zoe and Elmo create a face for Spongerino using stickers, paper, an eraser, and string. Now Rocco has the perfect friend to play with.
