Independence Monument

The Independence Monument is a treasure in, that can be found in the Back-and-Forth Road area. It could possibly be the leg of a toy robot.

Collecting the treasure
Near the end of the area, the player can destroy a dirt block, which will reveal a doorway. To access it, Olimar must use his Pikmin to push an iron block. On the other side of the doorway, the player will face a huge iron block, which requires at least 12 Pikmin in order to be pushed. After clearing the way, Olimar will get access to another doorway, that leads him to the treasure.
