A small creature that will jump at you and drain your blood, slowly. They would have way less health than a regular Turned, but be relatively hard to kill otherwise. They would run to you and jump onto your head, and slowly drain your blood. Killing them would be relatively easy, with a melee weapon (holding F or E for 20 seconds) or you could wait until they’ve drained most of your health and they’ll fall off.
Perhaps they’d drain your energy too, making it harder to run from other Turned in the area, and you’d have to stay in the same place. Other people could take them off your head easily, which could promote player interaction (perhaps)? Just a little idea, sorry if it’s kinda dumb
