This follows yesterday's Facebook unveiling of the blue variety.
Red Yoshi is now available as an unlockable QR character in Mario Tennis Open.
Revealed by IGN, Red Yoshi is available to unlock by pressing holding up and pressing the start button before scanning the code. Unlike regular Yoshi and Blue Yoshi (who focuses on speed), Red Yoshi has a focus on technique. The code will only work with the North American version of the game.
