Day 2 of Crabby's molt

As you can see, he has begun eating his exoskeleton, there is less of it left. He will continue to eat his exoskeleton to regain the calcuim that he lost during the molt process, this will help his body produce Chitin, which hardens his new skin into a brand spanking new exoskeleton.

Pretty gross that he eats his body that is left over. However, what is really gross is that if he had buddies in his crabitat, they too would be trying to partake in his exoskeleton.
