Koopa Paratroopa

A Koopa Paratroopa (or just Paratroopa) is a winged Koopa Troopa. They will loose their wings once they are jumped on.

Variations
Paratroopa's shells come in many colors such as green and red. In some older Mario games such as Super Mario World, there are also purple and yellow colors of Paratroopas. The paratroopa itself is always yellow with white wings.

Tip(s)
If you are in an area were you need to get to but there is too big of a gap in between and there is a paratroopa between you and the other ledge, then you jump on the paratroopa and bounce off of it to get to the other side.
