''A giant, red, robotic dragon built to be the protector of a Pure Heart. Fracktail has a long body with little arms and wings, and he shoots out of the ground into the air to attack Mario. The only way to beat him is to first jump on his back. You can then pick up the Frackles on his back and score damage by throwing them at his weak point--the yellow antenna orb. ''
