Their first appearance is in Super Mario World where they can be found in the Donut Ghost House and the Forest Ghost House. They occasionally turn transparent and reappear again with half doing one and the other half doing the other. Boo Buddies are known to be indestructible and must only be avoided.
There are also Boo Buddy Snakes in this game that are subspecies of Boo Buddies that are Boos all in a single line going in various zigzag patterns.
Boo Buddies reappear in Yoshi's Story where they mark their most recent appearance and can be found in the Ghost Castle. These enemies rarely swoop down at Yoshi and, unlike the previous game, do not temporarily vanish and can be defeated. All of the Boos cannot be defeated as more keep appearing.
Boo Buddies make a reappearance in Super Mario 3D Land as well. They act the same way they do in Super Mario World they spin around in a circle with one small opening of which Mario has to go through. The first group of these to appear, in the World 4 Ghost House, has a coin in it, spinning with the boos.
