ShellNumemon

KaratsukiNumemon is a Crustacean Digimon, whose name and design are derived from "Shell attached to Numemon" (『殻付きヌメモン』). They are sometimes called ShellNumemon, since they are the shelled counterparts of Numemon.

Digimon Frontier
A colony of KaratsukiNumemon resided on KaratsukiNumemon Mountain. Grumblemon took the women and children of the colony as hostages for the mountain's Fractal Code, so the males enlisted the help of the DigiDestined, who were there looking for food, and Koji, who had fallen into the colony while attempting to rescue the hostages. Takuya later announced that they were Legendary Warriors, causing the KaratsukiNumemon to believe that the DigiDestined were in league with Grumblemon, who was also a Legendary Warrior. After the DigiDestined fell asleep, the KaratsukiNumemon tied them to hanging ropes, and voiced their accusations. However, Grumblemon made an appearance and Slide Evolved into Gigasmon. He then sent the DigiDestined flying, separating them in the process, before absorbing the mountain's Fractal Code and leaving the KaratsukiNumemon without a home.

Some KaratsukiNumemon were later seen at the Autumn Leaf Fair. One of them in particular was singled out but was unable to help Bokomon find the Toucanmon who had stolen the boys' D-Tector.
