I am not sure myself..........maybe it has some kind of new ability.........like the Boos get extra Speed or something like that
I don't know.
Yeah, it was one of those game mechanics they added in. I mean I remember there was one in one of the Bowser created courses. And yes, Bowser himself made a few courses.
Wings can be added to enemies in the Course Maker. Without wings Boo Buddies simply circle an area. With the wings they move in and out.
