Sunnygo

Sunnygo 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, Sunnygo 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 Kinagi Town. Sunnygo's horn is a prized material, commonly used for jewelry and carving, as seen in the anime. Smaller Pokémon like Seadra and Lovecus are sometimes sheltered by Sunnygo's branches, and even offer it protection from foes.

Galarian Sunnygo were wiped out by sudden changes in ocean temperature, turning them into Ghost-types. Its body is a bleached white with half-closed pink eyes and a perpetual frown, and its arms and branches have a distinctly semi-transparent appearance to them; the branches can be used to take root inside and drain the life force of others.

The branches cannot cause injuries or pain, but they immobilize the victim until Galarian Sunnygo lets them go. They are commonly found in the remains of prehistoric seas, and while they can be mistaken for ordinary rocks, they will curse anybody who kicks them by accident.

In the Alola region, Hidoide and Dohidoide are natural predators of Sunnygo. However, they do not fulfill those roles in the Galar region, having not realized the branches of Sunnygo are delicious.
