Groosenator

The Groosenator is an object featured in Skyward Sword.

Location and Uses
Created by Groose, the Groosenator is a railed weapon equipped with a catapult that fires larger-than-usual Bomb Flowers. The Groosenator is accompanied by tracks that circle the Sealed Tracks, allowing it to freely move upon and aim anywhere. Groose unveils it to Link when The Imprisoned breaks free for the second time. Link and Groose must use it to temporarily stun The Imprisoned, allowing Link to land on it and strike the spike on its head. The third time The Imprisoned breaks free, the Groosenator will stun it and stop it from flying. However, the road to Groose's Bomb Flowers will become blocked by rubble, so Link must launch himself onto The Imprisoned's head to bury the spike into it and seal it for the final time. He can optionally do this anytime during the battles where the Groosenator is used, but it is required then.

The Groosenator is destroyed when the Isle of the Goddess lands back onto the Sealed Grounds, but the track surrounding the perimeter remains intact.

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.
