Koco (ココ, Koko) are mysterious stone-like creatures from Sonic Frontiers. They are found throughout Starfall Islands and made by the Ancients as like a vessel for them, holding the memories of them. Some wear attire or have other features such as the kind of plant on their head or no plant at all.
Some attire worn by them can also be thematic to the friends of Sonic that are trapped on the islands.
Some can also help upgrade Sonic's abilities. The Elder Koco can rise Sonic's speed and ring count, raising one tho will lower the other one. The Hermit Koco does Sonic's attacking and defensive power.
