Pincurchin is a marine, sea urchin-like Pokémon with a black body. Its face has two yellow eyes with black, triangle-shaped pupils on each of them; and two yellow, circular mouthparts. A line of sharp spines runs down its back, along with two other lines of two spines each on the side of its body. Each spine has a grayish tip which glows yellow when electric current runs through it.
