To get out of the Ice Cavern and move on with the expedition, there is an icicle puzzle the player must solve. The puzzle can be solved by moving all of the stalagmites and stalactites in such a way so that the entire pathway is cleared. When you return to the room, you can simply press a button next to the path to remove all of the obstacles. Solving the puzzle also allows the player to obtain the Party Puzzle stamp. Someone (probably Gary) possibly made the puzzle somehow, because after you finish it, you can just press the button on the side to clear the path automatically.
