Wind Waker Glitches - Solid Hole
- Go to Overlook Island (the top right island).
- Use your Hookshot to get to the highest of the towers.
- The one below the highest has an entrance hole on it. Face in the direction of the hole, back away from the edge a bit and do a jumping slash attack over the edge into the hole.
Your sword will hit the sides of the hole twice very quickly and you'll end up standing in the hole instead of falling through it. You can get out using your Hookshot or fall through the hole by backflipping, sidejumping etc.
