Telly, Elmo, and Rosita are playing Shape-O-Bots, robots that actually transform into shapes to help people. Andy, a guy in need of shapes, rushes in and explains that he needs an octagon to help stop people from crashing into him. Telly tries to transform into an octagon with eight sides and eight angles, but changes into a triangle with three sides and three angles instead. Rosita gives it a try and successfully transforms into an octagon, which Andy uses as a stop sign to stop people from running into him. Andy leaves but soon returns, this time in need of a pentagon, a shape with five sides and five angles. He explains that he is a baseball coach and needs a home plate, which is shaped like a pentagon, so his players won't slide right into him. The Shape-O-Bots do their thing and, once again, Telly changes into a triangle. Elmo is able to help, though, and transforms into a pentagon. Andy now returns one last time needing a rhombus, a shape with four sides and four angles, for the King of Rhombuses, who is missing his. Telly tries to transform into a rhombus, but, once again, winds up as a triangle. Rosita notices that a rhombus is actually two triangles stuck together. Chris suggests that since Telly hit his button one time to become a triangle, maybe hitting it two times will turn him into a rhombus. It works! Everyone is happy - especially the Shape-O-Bots.
