Weedle is a small larva Pokémon with a beige, yellow, or rust-colored segmented body. Combined with its red, purple, or fuchsia nose and feet, Weedle's bright coloration wards off its enemies. Weedle has a conical, two-inch venomous stinger on its head and a barbed one on its tail, but its other body parts are spherical.
Weedle can retaliate against attackers and those who step on it with its strong toxin. It can distinguish its favorite kinds of leaves using its acute sense of smell. As a young Bug Pokémon, its daily appetite for leaves matches its weight. Weedle can be found in forests and usually hides in grass, bushes, and under the leaves it eats.
