Some people requested a video for this trick, so here it is. 3 days ago I mentioned in the zelda IRC and on the forums how it was possible to skip the beetle using this BiTWW trick. Turned out that it wasn't possible since you can't equip the hook beetle without it. Even though have to get the beetle, this BiTWW saves a lot of time. And yes, I know that I played horrible in the boss key room, but this isn't a speedrun after all.
