Syakomon

Syakomon is a Crustacean Digimon. Syakomon is concealed in a sturdy shell shaped like a clam. Its shell developed rapidly, so its insides look like an in-training slime. This cunning creature entices foes with its cute face and attacks when they get close. When the shell is closed it has enough defensive strength to easily repel light attacks.
