It's a fantasy role-playing game.

DM: You are Beauregard Lionett called Beau, a human monk . You are the member of the famous group of adventurers. Previously, The party decides to leave it for now and possibly come back later. As they approach the Ounterloch which will lead them to the safe house, Febron is hit by another pollen blast and begins walking straight towards the lurking plant, but Calianna casts Levitate on him to keep him from stepping into it.
DM: Okay. As you tiptoe through the edges, leaping from cluster of root to cluster of root, being as quiet as you can, you come around the first tree where this figure had vanished, look around to where it's currently waiting and you see two trees that grew together and a large rock that's wedged at the base of it. Crouched below, behind the rock, you see this bulbous humanoid creature, with a deep green-blue skin tone with little pustules and boils on it, at the edges of the shoulder and arm. You see long stringy black hair that goes past the front of the chest. The torso appears to be swollen, this belly protruding beyond it. You can see hanging around the neck other pieces of hollowed bone, very similar to that chime that you saw being described by Caleb.
Player: Is it a troll?
DM: It appears to be trollish in nature. The pustules and part of its body, there's this thick green liquid that's oozing out in places. It's sitting there clinging to the rock with its long fingers, clutching it, looking over in the direction of where you were, breathing heavy.
Player: Does he see The Mighty Nein?
DM: It seems to be looking in the direction where you were.
Player: But he doesn't see me.
DM: He doesn't see you at the moment, no.
