Shaving Scream is a microgame in WarioWare: Smooth Moves. It is one of Wario's games. Its name is a pun on "shaving cream". Like Cutting It Close from WarioWare: Twisted!, it features shaving hair from a man's face.
In Shaving Scream, the player will have to use the Wii Remote pointer and shave Wario's face. Each level of difficulty involves the player shaving off more and more hair. After all of Wario's facial hair is cut off, he will blush.
