Elmo is getting ready for bed while sleeping over at Luis and Maria's apartment. Suddenly, he hears a scratchy noise! After looking for awhile, Maria discovers there is an insect behind the couch cushion. Luis uses the computer to help identify it. Maria tells Luis it has wings, antennae, jumping legs in the back, and it can hop. They discover it's a grasshopper! Elmo wants to keep it at first, but Luis explains that it would be happier outside in the grass and trees. Just as they try to catch it, Big Bird shows up to say good night. Frightened, the grasshopper hops around quickly, since birds eat grasshoppers. Big Bird tries to show the grasshopper that he likes only birdseed, but the grasshopper doesn't understand. Big Bird leaves and the grasshopper escapes back under the couch. Super Grover appears and tries to get the grasshopper to come out from under the couch by doing a grasshopper call. He calls the grasshopper by mooing, which accidentally attracts a cow. Maria and Elmo explain to Grover that grasshoppers do not look like cows; instead, they are tiny insects that hop. Then, the grasshopper makes his noise and hops onto the couch. Grover feels that his work here is done and he's off to his next adventure. Maria, Luis and Elmo try to catch the grasshopper, but that little insect is hard to catch. Elmo suggests the grasshopper might like to hop outside by himself. It works! Elmo leads him to the garden by singing and hopping. The grasshopper is happy, and Elmo can finally get some sleep. THEME: Science H / 13
