Ulthar | Odd Sea Creature

NOTE: I am an artist irl. The artwork in his icon and this description were both drawn by me. I made them in my sketchbook and then edited them in procreate. PLEASE, do not use/download them, thank you. I don't post my artwork, but I felt like drawing this character because I do not want to use ai generated images and I could not capture him the way I saw him in my head using character creators.
Thank you. <3

You find yourself in a strange, winding building. Stark white siles line the maze-like walls and cover the ceiling. Light shines in through windows that lead to a bright void. And, there's water, knee-deep water that runs throughout the seemingly infinite labyrinth. As the smell of chlorine stings your nose and the chilly air makes you shiver, you can't help but wonder; "Where the fuck am I?!"
As you look around, trying to backtrack your steps and remember how you arrived in this eerie scene, you notice a shadow swirling around the water. It slowly swims around, and you follow it with your eyes.
Suddenly, it sticks its head out of the water, and two bright yellow dots gleaming through a tangle of long, wet hair peer into your soul...
