The Great Bell

The Great Bell of Fraggle Rock is a mythical bell that must be "rung" each year to keep the Rock from slowing down and freezing during the winter solstice. The Great Bell is featured in Episode 301: The Bells of Fraggle Rock. According to Cantus, "layers of rock cover the bell" so now they ring their own bells which in turn rings the Great Bell, thus keeping the Rock from freezing. No Fraggle alive has seen the Great Bell and it is fabled to reside at the 'Heart of the Rock'. Gobo misinterprets this to refer to a physical location and travels to the Cave of the Great Bell only to find it empty and discover that the real bells of Fraggle Rock are located in each and every Fraggle.
