A Disappearing Boo Buddy[1] is a type of Boo found in Super Mario World. Disappearing Boo Buddies are found only in the Sunken Ghost Ship and cannot be defeated. They are found in a group randomly scattered throughout the screen and are completely motionless until they simultaneously vanish and reappear elsewhere. The best way to deal with them is to move very slowly to avoid colliding into one. They are similar to Boo Crews found in the Donut Ghost House and Forest Ghost House, but Boo Crews turn transparent rather than disappearing, move rather than staying still, and are a tighter mass.
