Mollusk(Japanese 蝸種) is a fan-made class by Democide of invertebrate monsters that lack the protection of a shell what makes them a lot more flexible in form. Many members of this class try to compensate the lack of protection with a self-made shell that isn't part of their original body, or the shell of another monster, in which they can retreat, others use different strategies to prevent getting injured. A lot of monsters in this class are aquatic and are able to swim fairly well or crawl on the ground. Because of the soft tissue and flexible form they can easily hide in different places that are unaccessible for other monsters of their size.
