The Coiled Launcher is a rusted spring in Pikmin 2. This treasure is found on sublevel 3 of the Subterranean Complex, where fire geysers and a few Armored Cannon Beetle Larvae are the only hazards, and there is an Ivory Candypop Bud to use. If all the enemies are in near each other, use a Captain to lure them into destroying each other with their rocks; if not, throw Pikmin on carefully, making sure the beast is facing away from any edges. The Coiled Launcher is located at random on the level. It is presumably a reference to the Gravity Jumper in the first game.
