The island is about 80 square kilometers, and is divided in 4 areas. South to east: Humid, dense, tropical coastal jungle. Normal, Flying, Bug, Electric and Plant Pokémon live here for the fruits and edible plants. A stream coming from the Misty Hill runs through it. On the East, there are coral reefs and shallows with lots of fish. There's a calm bay south. Northeast: Dry, arid Shrublands, with rocky soil, cactuses and large rocks useful for building. Ground, Rock, Steel and Fire pokemon are more common. The Northern sea has strong currents and rougher access, so there are some rests of abandoned boats. Central West: Misty Hill up to 600 meters or 2,000 ft. The moss, constant fog, twisted trees and cool climate attract Ice, Fairy, Psychic, Fighting and Dark Pokémon. Origin of a freshwater stream. Rare mushrooms and medicinal herbs are also found here. The surrounding sea is deep and calm, with underwater caves. Northwest: Coastal Swamp, a wetland with still water, mud, and aquatic plants. Poison, Water, Ghost and Dragon Pokémon roam around this place. Ideal for gathering clay, herbs and rare berries. The island has a heavy rain season of 4 months, with light rain the rest of the year. Normal animals coexist with Pokémon in this island, adapted to each of the 4 biomes.
