#0012 Butterfree -- Pokedex Series (Patreon)

"In battle, it flaps its wings at high speed to release highly toxic dust into the air. Its wings, covered with poisonous powders, repel water. This allows it to fly in the rain. Its wings are covered with poisonous dust. If you see one flapping its wings, be careful not to inhale any of the dust." -- Pokemon RBYSt
