Rainbow Flutter

Rainbow Flutter is the Offensive Power Shot used by Yoshi in Mario Power Tennis. Yoshi performs a Flutter Jump in the air and then hits the ball, which leaves a rainbow trail behind it. This may be the inspiration for the Flutter Dunk from Mario Hoops 3-on-3.

This power shot is able to hit the ball even if it's very high in the air, and is in fact the only Offensive Power Shot capable of doing this.

Trivia

 * A similar move as a Super Move is present in Table Tennis in Mario & Sonic at the London 2012 Olympic Games.
