Magic Paint is the Offensive Power Shot used by Bowser Jr. in Mario Power Tennis.
Description[]
Upon activating the move, Bowser Jr. gets out his Magic Paintbrush, moves toward the ball, then paints it. Bowser Jr. also creates two paint balls to try and trick the receiver, and sends both of them and the disguised tennis ball to the opposite side. The ball in the center is always the actual tennis ball. The paint slows the receiver's movement temporarily.
