Styx Swimmer

Hydroloths were hideous amphibians that resembled squat humanoid toads and stood ten feet tall when standing, although they were more often resting in a crouched stance. Their skin was warty, yellow, covered in mucus, and adorned with ancient, intricate symbols. They had frog-like faces that hosted a pair of bulbous eyes, webbed digits ending in claws on their hands and feet, and gliding flaps under their arms
