Caterpie is a serpentine Pokémon that resembles the larvae of the Spicebush Swallowtail. It is a green caterpillar with yellow ring-shaped markings down the sides of its body. It also has large yellow eyes with black pupils. Its most notable characteristic is the bright red antenna (osmeterium) on its head, which releases a stench to repel predators. These and the large eye-shaped markings help to startle predators. Its feet are tipped with suction cups, permitting this Pokémon to scale most surfaces with minimal effort.
