Giant Sea Worms are oceanic creatures that inhabit the Tully Observatory station of the McDuck sub-lab. According to Fethry Duck, these worms were mutated by the toxic vents of the station and want to squeeze the warmth out of their victims. They can be pacified and let go of their victims if one can convince them you're not a threat since they can detect fear. The Giant Sea Worms appeared in the DuckTales (2017) episode "The Depths of Cousin Fethry!"
