Monstruo colosal de alcantarilla con fauces dentadas y tentáculos

A gargantuan, Maw, slimy tongue, with thick, rough scales, translucent skin and a mesh of gnarled, pulsing veins, stares menacingly with horrible, mean eyes with a wide, toothy mouth agape, revealing rows of jagged, yellowed teeth. The upper maw is a mass of bony plates, while the lower part of the maw extends into many root like tentacles that allow it to move around the storm sewer system of a city. There are bones and skulls of its victims laying around as it moves through the very dirty storm sewer. Done in a fantastic, colorful and dynamic fantasy art style.
