Also known as: キュッキュ君
A mysterious, phallic, rainbow-colored creature from Yume Nikki. Kyukkyu is found within Madotsuki's dream, behind a secret space in the wall in the "Numbers World". His sole action in the game is to suggestively rub a nearby guardrail; interestingly, he speeds up his strokes when Madotsuki draws her knife.
