Curse of Strahd
The origins of this horrific plant are utterly unknown, as is much important information about it. The reasons for this are numerous, but center around the difficulty of coming into contact with the creature to study it and living to record one’s observations. In appearance, the doppelganger plant looks much like any of a variety of melon-bearing crops. It spreads out in a tangle of vines and broad, glossy leaves. Scattered throughout its mass are a number of pods, each measuring between four and eight feet long. These pods are the source of the wicked creature’s intelligence. They also serve as its main form of self defense as they are able to dominate the minds of others and make them serve the plant’s will. The doppelganger plant cannot communicate with those it does not control, but is able to instantly exchange information and instructions with those it has taken over. In this manner, the doppelganger plant knows and experiences all that its minions do and see.
