Gricks are creatures within the Critical Role, Dungeons and Dragons, and Pathfinder universes.
Creature Information Edit
They resemble large blue and purplish worms with beaks, and four small tentacles that surround their mouths. They are very fast and seem to sense movement. They are aberrations that reside in the Underdark.
Very little is known about gricks in the world of Critical Role since they have only been seen once and were destroyed almost immediately using a combination of Tiberius's Fireball spell and Percy's homemade bomb.
