Bonitaville (Japanese: ブロウタウン Blow Town) is an anime-exclusive town in Johto. It is located between Goldenrod City and Ecruteak City.
Every once in a while, a Pokémon Beauty Contest is held there. In the anime, Ash, Brock and Misty met up with Suzy, from which Brock got his Vulpix. She wanted to enter the contest, and as such Brock also wanted to enter. They decided to go as a couple with Vulpix. Another Pokémon Breeder and a friend of Suzy's, Zane, also entered the contest with his Ninetales. After the contest, Brock returned Vulpix to Suzy.
