Groosenator

As seen in Skyward Sword

The Groosenator is a cannon that fires Bomb Flowers larger than the usual Bomb Flowers. It is very helpful when sealing The Imprisoned. It stuns The Imprisoned for a good amount of time. As its name suggests, the Groosenator is built by Groose, accompanied by wooden tracks that circle the Sealed Tracks, allowing the Groosenator to freely move upon and aim at The Imprisoned.
