The Anguins only come when the moon is blue and the sky is purple. This kind of strange night only happens once every 65,000 years. These little creatures try to enjoy this night as much as they can. You have the power of the blue moon, so use that power to make this night awesome for everyone, especially the Anguins.
Blue speeds them up. Grey slows them done. Red makes them fall in love. Light grey makes them argue. Orange makes them hungry. Black makes them wrestle.
