Using a Healer in Rauru, it is possible to wrong warp in the game. If you talk to the Healer on specific frames she will turn around and open the door. This allows Link to enter the house and end up in a glitched town.
Unfortunately this is a really precise trick. The Healer moves every 2 frames so it may appear as if you talked to her at the right time but you could be a frame off. Talk to her the first time when her nose hits the window. The 2nd time you talk to her elbow is touching the window. It is common for people to mash the 2nd time talking to her.
