Crawlers are reanimated babies like the Lurker. A Crawler's skin is the same pasty gray as the Pack's . The torso is grossly enlarged with an organic explosive under its skin. The limbs are twisted backwards so it can move with the sac pointed upwards. The back legs of the body are fused together, giving the Crawler an almost caterpillar-like style of movement. The Crawler combines the Lurker's mobility and the Exploder's lethality. If they are killed without hitting their explosive sac (for example, cutting off the head), their bodies can be picked up using kinesis and used as a weapon against other Necromorphs , similar to the Exploder's explosive sacs. Live Crawlers cannot be picked up using kinesis.
