Mad Boos are Boos that appear in Super Princess Peach. Mad Boos' behavior is the opposite of that of a regular Boo; Mad Boos do nothing when Princess Peach turns her back to them, but if she faces them, they will approach her. Like regular Boos, Peach can defeat them with the Rage Vibe. They also appear in a rarer Big Boo form called Mad Big Boo.
