Roper
Creature
The Roper is a patient horror of the deep caverns: a tall, mottled creature that stands utterly still among the rock formations, indistinguishable from a stalagmite, until prey wanders within reach of its sticky, far-reaching tendrils. It lashes out with these, snares its victim, and reels them slowly in toward a great toothed maw, taking its time. A party can pass within arm's length of a Roper and never know it, and only realize their error when one of their number is suddenly, silently jerked off their feet and dragged toward the rocks.
