Corsola

Corsola (Japanese: サニーゴ Sunnygo) is a /-type Pokémon.

Appearance
Corsola is composed of a pink coral-like substance. It has a small face and a white underbelly. In addition to the coral outgrowths (also described as branches) situated all over the upper half of its body, Corsola also has a growth like a horn on its head, and that is considered its natural armament when facing underwater predators. The branches serve to supply Corsola with nutrients by absorbing them from wherever there is clean water. The branches are amazingly expendable; if any branch breaks off, Corsola can grow it back over the period of one night (compare with Staryu). However, this fragility is undermined by Corsola’s inability to live in polluted water. If the sea is polluted, Corsola’s branches become discolored and soon crumble away, where soon after the Pokémon will die.

Special abilities
Corsola has the ability Hustle which its shares with six other Pokémon. Its second ability is Natural Cure. Due to its appearance, it seems that Corsola could easily disguise itself as a rock or coral to avoid being eaten/attacked.

In the anime
In the Pokémon anime, Misty caught a Corsola in the episode A Corsola Caper, and has owned it ever since. It almost immediately became Misty's primary battling Pokémon, displaying surprisingly strong offensive abilities (in one case, knocking out a Gyarados with a single attack) in addition to the defensive power for which the species is best known.

Evolution
This Pokémon does not evolve.

Origins
It is obvious that Corsola is based on a coral. Its name is derived from coral and sole.
