Corsola

Corsola appeared in 1999 video game called Pokémon Gold & Silver. Corsola is a Coral Pokémon. The coral branches that are on Corsola's head are fairly fragile and often snap off, but they're good as new after a few days of regrowth. Corsola sometimes breaks off its own branches to use as a decoy when it's being chased.

Corsola is composed of a pink and white, 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.
