They first appeared in Mortal Kombat II in the Living Forest level, where they occasionally roared. This background also appeared in Mortal Kombat Trilogy, and as a 3D arena in Mortal Kombat 4, Mortal Kombat Gold, and Mortal Kombat: Deception. Deception's Konquest mode allowed the player to venture into a forest of Living Trees, though the player could not interact with them.
