Stalk lurks in vents and if a player stays in for about 5-10 seconds (similar to hide) Stalk will grab them and pull them into the wall. Players may need to scramble out and come back in to avoid Stalk. Stalk takes the form of a black hand, however it's jumpscare features a figure slamming them into the floor. This entity won't attack if you are passing through the vent, however if it senses that you are not moving or have not passed a corner, it will attack.
