This pokemon papercraft is Corsola (Sunnygo), a dual-type Water/Rock Pokémon, based on the anime / game Pokemon, the paper model was created by javierini. Corsola is not known to evolve into or from any other Pokémon. There are other two Corsola papercrafts on the site: Pokemon Papercraft - Corsola Ver.1 and Pokemon Papercraft - Corsola Ver.2.
Corsola is a small, pink, roundish Pokémon with branch-like growths on its back, which are similar to coral. There is a smaller, blunt horn on its forehead, and it has black, oval eyes. It has a white underside, which speckles towards the sides. Its four legs and two arms are blunt and stubby. Found in the warm shallow waters of southern seas, Corsola requires clean water to live. If its habitat is dirty, the growths on its back become discolored and degenerate. However, when it is healthy, its growths regularly shed and grow back. It is able to regrow them over the course of a single night. It forms large social groups. Occasionally these groups get so large that people may live atop them, as is the case in Pacifidlog Town.
