Pikmin 2/Unused Caves/last 4 Dungeon

This is a sub-page of Pikmin 2/Unused Caves/last 4 Dungeon.

All floors in Last_4 are enemy test floors, some of them with layouts that don't appear anywhere else in the game.
Given the cave's file name, this would have appeared in the Wistful Wild during game development.
