Overview: Elmo, Abby, Grover, and Nina want to make an obstacle course on Sesame Street. But they don’t have anything to go over, under, around, or through. They wonder what they can find around them to make these obstacles. What if they use a broom to go over, a blanket to go under, pool noodles to go around, and a cardboard box to go through? It works! The friends made the best monster obstacle course ever.
