Groosenator

The Groosenator is an object featured in Skyward Sword. Created by Groose, it is a weapon equiped with a cannon that fires larger-than-usual Bomb Flowers. The cannon is accompanied by wooden tracks that circle the Sealed Tracks, allowing the Groosenator to freely move upon and aim anywhere. The Groosenator becomes extremely helpful when sealing The Imprisoned during the second and third times that it escapes since it stuns beast for a considerable amount of time.

Whenever Link needs to use the Groosenator, the Up button on the Control Pad must be pressed to set up the shot. The machine's position can then be adjusted with the Control Stick while the target is aimed at with the Wii Remote, and the A Button is used to fire the Bomb Flower. Once Link fires the Groosenator, he must wait until Groose shouts at him to let the young hero know that the cannon is ready to fire once again.

During The Imprisoned's third escape, Groose is unable to access his stash of bombs due to it being blocked by rubble. Link is then forced to get into the Groosenator as Groose fires him onto the Imprisoned's head, where the young hero buries the spike into the beast to seal it once again.

The Groosenator is destroyed upon the Isle of the Goddess' landing onto the Sealed Grounds, but the track surrounding the perimeter remains intact.
