Clotty appears to be a living blob of blood with a bone in its head, making its appearance to resemble a meat.
Clotty slowly crawls in random directions, shooting blood projectiles in the cardinal directions every three seconds, making it hard to hit without taking damage. If there are multiple Clotties in a room, the use of bombs or activated items like The Necronomicon is highly recommended. Having spectral or homing tears will make engagements with them much easier as well.
