Orange Islands

The archipelago is different climatically from Kanto, which is temperate while the archipelago is tropical. One effect of the different climate is that Pokémon found in the Orange Islands have different patterns or colors than are found on the main land. In addition, several of the islands feature unique Pokémon found nowhere else: one island is home to a rare fruit that turns Pokémon pink if they eat it, and another island is home to an Onix whose body is made of crystal rather than rock.
