Living Trees | Mortal Kombat 4

The Living Forest is an arena located in Outworld. This forest has been haunted for centuries. The trees themselves are alive, some with faces that groan and roar. Some of the trees are hungry, and unsuspecting traveler may find themselves ensnared in their treacherous branches, and become devoured. In turn, those consumed become part of the forest. - Mortal Kombat Wiki
