Ten-year-old Kasman wants to be an eco-ambassador for all-seasons, and the Green Squad can't wait to help him out! Kyle tests Kasman's recycling knowledge with a fun game using his household trash, and takes Kasman to his municipal recycling facility to get a backyard composter of his very own! Eric shows Kasman how to care for his backyard in preparation for winter, and gets him started with some herbs indoors so he can transplant them outdoors in the spring. Shakira and Kasman program his thermostat to save on energy, and are on the lookout for drafty doors. Together they make some scrappy door snakes out of second-hand fabrics to block out the cold. Kasman and his family will definitely be keeping warm all year long! Green Squad sees five passionate and environmentally-savvy young hosts challenge other motivated kids and their families to make fun, eco-friendly lifestyle changes for a healthier planet.
