Mollusca is an enemy in Castlevania: Dawn of Sorrow. It is a monstrous mollusk imbued with the castle's dark power.
The Mollusca is a giant slug-like enemy; it has no shell and attacks by poisoning its target on touch.
Its soul, Summon Mollusca, allows to spawn a Mollusca in front of Soma, which advances forward damaging anything it comes in contact with.
The soul is also somewhat valuable as it is required at one point in the process of forging the Joyeuse (combine it with a Fragarach to forge a Hrunting).

- A more advanced version of the Mollusca, the Giant Slug, actually has a snail-like shell with spikes.
