Photolith

The Photolith is a metal object in Pikmin Forever. It is a Crookes radiometer. It is found in the Mycelial Burrow, after the section in which Mushroom Pikmin is found, on a ledge that requires activating a light sensor to reach. When Mushroom Pikmin or leaders approach the Photolith with their light, the foil fins inside rotate, since the object measures light.
