Poop is usually a Pigeon, Starling, or a Robin in Hillscape1 who constantly defends any source of water, mainly the river, and tries to keep competitors away. He will kill anyone who goes near the water without mercy and usually says "MY WATER!!!!!" to warn people to stay away from that source.
He is also in Test Terrain and usually appears as a Bunny. He likes to keep people away from all ponds, so he can swim in them himself. He hates talking/socializing with anyone in-game and tends to like playing by himself.
