Planet Granite is a planet a million light-years from Mobius and was the first destination on Amy Rose and Tekno the Canary's journeys through the Ring of Eternity. When the heroes visited Granite, the planet was in its early stages with the natives in the initial stages of civilisation. Two rival tribes were the Meek Tribe and the Thickskull Tribe. The latter were warlike and frequently enjoyed attacking their cowardly neighbours. Instead of providing them with a crossbow to defend themselves, Amy convinced the Meek to mock the Thickskulls and encouraged both sides to talk things out.
To Amy's horror, their appearance introduced cucumber sandwiches to the planet.
