Ten-year-olds Emma & Monica are two best friends living in a small town, but they want to make a big difference! Together with Sigfried, Shakira, and Kyle, the girls get organized and meet with the town council to propose their ideas: they want to spread their message with an Earth-saving mural in the park pavilion. The town councilors love it! Later they get to work and create a bold look with Shakira, making flower-hammered t-shirts for their garbage collecting team. Once the shirts are ready, Kyle leads the way for a town-wide garbage walk with Emma, Monica, and all their friends and family. With cleaner parks, roads, and rivers, the Green Squad finally says goodbye to the girls. And in their check-in, Emma & Monica show off the beautiful mural they made to encourage others to keep their small town clean and beautiful. 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.
