The Glass Eye is a Scavenger Hunt item located in the GPC and Wilderness in Whispering Rock Psychic Summer Camp. It is trapped behind a grate at the end of the stream and must be retrieved with Telekinesis.
It is unclear whose eye this is; the description seems to imply that it belongs to Ford Cruller, though both his eyes are blue. It may belong to Coach Oleander, as his eyes are naturally green (as seen as a child), but one of them is brown, indicating it may be fake.
