8. Bills Secret Garden
Despite having only a minor role in the games, Bill has emerged as something of a fan favourite. The mysterious Pokémon expert appears in the original games, as a friend of Professor Oaks. At one point, the player visits his house in Cerulean City in order to get information about the Pokémon storage system and gain an S.S. Anne ticket. Keen-eyed players noticed that there was a strange path leading from Bills garden to a hidden area, sparking myths of Bills Secret Garden. The theories varied, but most concluded that the area must contain one or more legendary Pokémon for players to capture. Actually getting entry to the garden proved problematic, though some swore that you could access it after completing every Pokédex entry, or by talking to Bill after capturing Mew. The search was fruitless though, and using cheats to access the hidden area shows it off as a completely empty, featureless space.
