Origin
A Zhu Tun She, also known as a Chotonda or a Snake Pig, is a half-snake monster from the Yijian Zhi, a Chinese collection of stories, written during the Song dynasty. Despite being described as having a snake-like appearance, it has four legs and acts like a pig, making squealing sounds.
Design
It appears as a small pig with green vegetation growing on its back and a white underbelly. The horizontal stripes cross its back causes it to resemble a watermelon. It has large yellow eyes, resembling those of a reptile's, a horn coming out of its snout, and claws on all of its legs. The white part of its belly goes up and swirls around its cheeks.
In the Devil Children series it appears as two mushroom-shaped green pigs on top of each other with much smaller eyes, and a brown underbelly.
