Unmarked Ore Series

The Unmarked Ore Series is a collection of metal objects in Pikmin Forever. These are mostly naturally occurring metals or minerals from which metals are extracted. Some of these objects are not naturally occurring, but their pure, untouched appearance fools Olimar and crew. Olimar's notes on this series probably contain the most metallurgical science of any of his notes, since he is in awe of the breadth of metal compounds and properties on PNF-404.
