Zaqqum

A self-aware tree that has a face. It often slips in with other trees, and waits silently for its prey to approach. Sometimes it grows a delicious looking fruit on its branches to lure its prey, but the fruit is very bitter and inedible. When the temperature drops, it enters a state similar to hibernation. In that state, they become sluggish, so most of these monsters are found in relatively warm areas.
