Moles are enemies found in the Mines. They move towards the player by tunnelling underground, leaving short trails of uprising dirt. When they get near Isaac, they emerge from the ground and spit a packed cone of 3 blood shots at him before leaping out and tunnelling back into the ground upon landing. Moles can only be hurt in the short time they spend out of the ground. When Moles leap, they also have a chance of creating permanent gaps in the ground where they were. In Rooms under a Curse of Darkness effect, Moles will have their eyes open and glowing in the dark, though this does not affect their behaviour.
