Mad Boo

From the Super Mario Wiki

Mad Boos are Boos that appear in Super Princess Peach. Unlike regular Boos, Mad Boos do nothing when Princess Peach turns her back to them, but if she faces them, they will attack her. They also appear in a rarer Big Boo form called Mad Big Boo. Unlike other Boos in Super Princess Peach, they will not be defeated if Peach uses Rage on them.
