Weedle is a small, yellow, orange, or brown larva Pokémon with a segmented body. Combined with its red, pink, or purple nose and feet, Weedle's bright coloration wards off its enemies. Weedle has a conical, two-inch poisonous stinger on its head and a barbed one on its tail, but every other body part is 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.
