In warm seasons, Vilefing generates excessive clouds of pollen, leading to an orange haze in its environment that irritates breathing. The buds on its body grow to large sizes until it cannot hover, after which it must shed them.

Getting up close to a Vilefing will give you a chance to observe, through its thin skin, the toxic gases swirling inside. In seasons when it produces more pollen, the air around a Vilefing turns yellow with the powder as it walks.
