Chinchou is a small, round, blue fish-like Pokémon with a pair of tiny white fins and two small blue feet. Chinchou's eyes have unique pupils that are shaped like plus signs. It has two antennae that are positioned on its rear like two tails. There is a yellow teardrop-shaped orb at the end of each antenna. The electricity-generating cells in these antennae create so much electrical power that they even make Chinchou tingle slightly. Chinchou charges up its electric attacks by absorbing energy through its two antennae, and flashes its electric lights to exchange signals with others. Chinchou tends to lurk on the dark ocean floors, rarely ever coming up to the surface. However, it has demonstrated the ability to walk on land.
