On its head, Weedle has two beady, black eyes above a large, pink nose. The stingers and bright colored bodies of these Pokémon are intended to ward off predators who would not enjoy it's toxins. Weedle also have a sharp smell, using their nose-like proboscises to find which leaves are safe to eat. They're voracious eaters.
