Internal-Clock Measurer

The Internal-Clock Measurer is a treasure in. It can be found in the third sublevel of the Drafty Gallery. It is a mechanical. The exact number displayed on it, being 2001 almost ticked over to 2002, is likely a reference to Pikmin releasing near the end of 2001 in Japan and North America. If this reference is intentional, the word "Internal-Clock" might also refer to the Nintendo GameCube's internal clock.
