The Alola region is made of up four natural islands and one artificial island. The Alola region is a popular resort destination and attracts a lot of tourists from other regions. Due to the unique environmental pressures, a number of Pokémon species that appear in Alola have regional variants known as Alola Forms that have different properties to elsewhere in the Pokémon world. For example, in Alola Vulpix moved to snowy mountain peaks to avoid the normal habitats of other Pokémon, and adapted to their new environment by becoming Ice-type.
