Even though Poison Mushroom Cookie appears as an antagonist of the Cookie Run: Kingdom game, this Epic Cookie with purple clothes still looks very cute. Actually, this cookie is very small with deep brown dough and wears a dark violet tunic with long, periwinkle sleeves. Poison Mushroom Cookie features a unique zigzag-shaped mouth and purple, sunken eyes in our fanart Cookie Run Poison Mushroom Cookie Sticker.
