Here is a kind of… odd? Creature. It has 4 legs but can stand on 2 at times. This creature has 2 heads that share a brain. With how they work it’s usually one acts as the main head taking in information and sending it to the other, but that head receiving the information is probably sleeping so some of the info may be messed up. The sleeping head also acts as a tail and will awake when the other head sleeps. Unless they get hurt, then both will get up and it will have to stand on all 4s. They have parts on them that resemble a parasite.
