Elmo, Abby, and Chris are helping Zoe make a habitat for her new pet gecko, Gary. They fill a terrarium with soil, moss, rocks, and branches but are missing a hiding place to keep Gary cool. This is a problem! They wonder what they can use for Gary�s hiding spot. What if they use an empty yogurt cup? Let�s try! It works. They didn�t give up and made the perfect hiding spot for Gary�s new home.
