Skyward Sword has only just come out, but already people are discovering some glitches! Here are a couple of funny ones I found on YouTube.
1. The Pillar of Death
If you run up to a rocky pillar at the Eldin Volcano in a certain way, Link falls through the floor to his death into what looks like a portal to hell!
2. Bathing with the King
In one part of the game, you're able to peek at the Knight Academy Headmaster taking a bath. But a glitch allows you to get up close and personal with him!
Edit: This 'glitch' has actually been confirmed as a hack, that is possible only by editing the game/using third-party software.
