In calm, secluded seas, Corsola grow to tremendous sizes. A classic sailor’s tale is a Corsola the size of a reef, moving across the seafloor to foul ships and ruin maps.

Although the seas around Galar support other life, efforts to reintroduce Corsola to their beaches end in failure. Occultists believe reintroduction will fail until the ghostly Corsola hear an apology, but Pokéologists reject the theory.

Although Cursola’s ectoplasm protects its body, there’s even more danger if you touch the real core. When a Pokémon touches Cursola’s real body, their fates are said to twist together. Cursola will ruin its own day afterward just to spite the one that hurt it.
