Key Stones are objects that first appeared in . They are small figures that can used as keys to open sealed doors or paths by placing them in matching pedestals.
In general, Key Stones are figures that come in sizes ranging from slightly smaller than
Sonic's full height to about the size of a head. Each Key Stone have a square rock stand with a figure fixed on top of them, which is usually a lump of crystal, but also sometimes a statuette. All Key Stone types come in different designs and colors. They can be found lying around in specific places in the game's environment.
Key Stones are used to unlock paths and doors blacking the player's path. To unlock such paths with a Key Stone, the player has to
grab a Key Stone and take it to a nearby pedestal with colors or symbols matching it and then insert it there by releasing it, which will then unlock the path. If a Key Stone is inserted into a non-matching pedestal, nothing will happen. However, if inserted or just placed in the proximity of its pedestal, the Key Stone will automatically insert itself.
While carrying a Key Stone, a playable character's speed is lowered and their unique actions cannot be performed (e.g. Sonic's
Sonic the Hedgehog's Spin Dash, Tails's Propeller Flight, Sonic the Werehog's Skills etc.).
