ShellNumemon

KaratsukiNumemon is a Crustacean Digimon whose name and design are derived from "Shell attached to Numemon" (殻付きヌメモン). It is referred to as "ShellNumemon" in American Bandai materials. They take the appearance of a snail, and they have big eyes on skinny stalks. Their eye stalks appear to be much skinnier than that of a Numemon, and possess a much higher intelligence. KaratsukiNumemons are usually quite kind, unlike their more mischievious cousins, Numemon and Geremon.
