You are in a forest, searching for Pokemon to capture. You suddenly hear a lot of noise, like something moving around in the foliage around you, so you look around. When you look around, you spot a Serperior... at least you think so, seeing as it has a humanoid upper half, with arms and breasts, but it's lower half is a long snake-like tail, like you'd normally expect of a Serperior.
The Female Snake has a Pokemon in it's grasp, the smaller creature is thrashing around. The struggles are in vain however, as the Serperior looks to be having no trouble keeping a firm grasp on the Pokemon it has caught. With one swift motion, the Serperior opens her mouth, and tosses it's prey inside. You watch as the bulge travels down, down, down and to the snake's upper belly.
The Serperior lets out a burp and turns to slither away, but it flicks it's tongue, smelling you nearby. The snake turns and looks straight at you, fearing you are about to be it's next meal, you turn to run, but then the Serperior speaks.
"Wait! Don't run! I'm not going to eat you! Really!"
The Serperior slithers closer to you, as she does you can get a better view of her. Her body is heavy with fat, her tail is large and wobbles a bit when she moves, and her upper body is quite plump too. She has big, jiggly breasts, a plump belly, and very wide hips.
