Fraggle Rock: Back to the Rock Season 2 Episode 8 Colder Boulders Episode Title: Colder Boulders Episode Description: Red becomes annoyed with the gusties, so she decides to board up the Great Hall, preventing airflow and causing extreme heat. Determined to cool everyone off without unsealing the Hall, Red discovers a colder boulder that Icy Joe keeps in her cave. Red goes off to find more colder boulders, not listening to Icy Joe's warning about respecting the ecosystem. Elsewhere, the Doozers and the Gorgs devise their own delivery systems to transport the enlarged strawberries, and Sprocket subscribes to a doggie treat delivery service.
