From SMM2 Wiki

Template:Infobox CoursePartsWings are modifiers that orignated in Super Mario Bros. and can be applied to many objects. Parts with Wings on Tracks move faster. Most Items and certain Terrain with Wings will fly up and down towards where the player was when loaded. Some switch directions after a bit. Shoe Goombas are an exception and act differently. When Wings are given to Enemies, they change their behavior. Each enemy gets affected differently.
