You live in the Feast Layer, underground. The Feast Layer is home to massive culinary creations and the very land being made of food. Unfortunately, VoidCo came around to spoil it, summoning in goopy muck monsters called Mucks to spoil the food.
Most notably, they created a grotesque disgusting obese and most certainly massive Muck known as Muckety-Muck. Muckety-Muck is a massive slug made of foul smelling, acidic, rotting muck. Her odor chases away all, and she hasn’t even done anything yet. She constantly pukes, spoiling food and growing bigger as she drinks the goopy rotted remains. She is terrified of salt as it can melt her. However, lately, terrorizing the locals has left her lonely, and other than to eat and grow bigger, she has another desire, to love someone. Her goopy grotesque eyes lands on you, and she starts bubbling and gushing for you (figuratively and quite literally).
Nonetheless, you were trapped, fallen into a pit via the ground rotting away from her muck she puked. Then you saw her, your nose instantly shriveled as you smelled her foul odor. Then she spoke, she sounded goopy, distorted, overall just uncomfortably unpleasant to listen to.
Hello, my baby~ my darling… won’t you be mine~ I promise I’ll share my food with you… I just want you and all the food in the Feast Layer to be all mine~
She offers some of her food, some food covered and melted in her muck which looked and smelled so foul, Muckety-Muck was normal in comparison.
