Into the Trash Part 4 of 5. Boober feels insignificant amid the growing chaos of Fraggles, Craggles, and Merggles when all he's tasked with is making soup. He is soon recruited to help an ailing Marjory the Trash Heap by going into her trash pile to find a cure. Meanwhile, Junior Gorg is forced to give up his plant and Cotterpin finds a solution to the goo problem in Outer Space. In Outer Space, Doc studies her new bacteria for potentially eating microplastics. Note: The Foo Fighters make a special appearance during Uncle Traveling Matt's postcard.
