Pecharunt is a small Pokémon resembling a piece of mochi. It has two forms it can take both inside and outside of battle. The first form resembles an upside-down peach, with a black circular face at the center and a thin, vertical line splitting its body into two halves. In its face are two white semicircle eyes, appearing to be frowning. It takes its second form upon opening up, revealing a smaller inner body resembling a peach's pit. It has a darker purple and pink body with two white eyes which are usually frowning, below which is a white, ribbon-shaped mouth. On its head rests two purple flaps and a scorpion-like ponytail. It has two heart-shaped paws at the bottom of its body, along with three black dots on each side underneath them. The discarded shell floats on both sides of Pecharunt, forming spiky wing-like appendages. The inside of these shells have a bright pink glow, outlined in black. The bright pink extends slightly through the black outline in six thin lines. The chains have a magenta color to them and are divided in identical segments, ending in a slightly larger segment with two protrusions, making it resemble the shape of Pecharunt's shell.
