Giant Crustacean

Giant Crustacean (巨大甲殻生物) was a monster from the New World that appeared in Mass for the Dead.

Appearance
A giant crab with a hard shell and claws. Some can grow to be quite large, enough to fill the passage of a cavern.

Abilities
These creatures can grow in size due to continuous undisturbed molting over time.

Trivia

 * This creature did not actually make an appearance, in the game, though it is killed off-screen in the game by the Pleiades.
 * One was blocking a passage to a hidden pirate hideout on a deserted island. According to Solution Epsilon, based on one specimen it's shell was elastic and looked quite new, indicating it may have recently molted. It was nocturnal, and emerged from the cave at night, and may have been over two hundred years old as it was used by pirates as a living door for their hideout.
 * Later in another special event, giant crabs were featured though they were of a smaller variant found in the seaside of the Re-Estize Kingdom.
