A weird occurrence was occurring at the Mushroom Gorge. All of the red bouncy mushrooms both outside and inside the giant cavern within the bluish green mountain were suddenly disappearing, with only the green colored non bouncy mushrooms remaining. The normal green shelled Lakitu who acted as a referee spotted this high in the clear blue sky, shocked as the white puffy cloud he was riding on gasped in shock.

"Oh good lord! The bouncy mushrooms!" Lakitu exclaimed as he zipped down to the wild racecourse. "They're just disappearing! What is going on?"

As Lakitu continued questioning the weirdness of the course, the Goombas found at the wild bend near the finish line were suddenly squished by a strange, powerful force, with the force being Kamek, who has returned to the Mushroom Gorge to cause magical mischief once again, cackling with glee.
