This glitch allows the player to go behind Bill's house to a place known as "Bill's Secret Garden."
- A Pokémon that knows Surf.
- Go to Bill's house, then go to the third tile to the right of the bottom of the right side pool.
- Hold down the up button as START is pressed.
- Save and reset the game.
- After the game reboots, use Surf. The player should Surf into the wall.
- From there it is possible to Surf into the water, and from there the player can Surf to behind Bill's house.
Bill's Secret garden used to be a place where Pokégods were thought to be.
