Nudity: 2 to 4
This doujin puzzle game's object is to arrange sections of pipe to bridge a connection between two nodes via sliding tiles. You must use all the pieces of pipe and connect to the correct side of each node, or else the stage continues. For each stage you complete, a blue-haired girl (Tomo-chan, I'm guessing) will strip to the delight of dancing bunnygirls. You only get a certain number of moves for each stage, although most stages won't require you to use each move.
