A beautiful plant can be turned into a carnivorous plant whereas a fairy animal can turn into a ferocious creature. It allows the user to take the appearance and powers of the fairy animal. Wild magic is the first step to gain the ultimate power of the fairy animal which has the first color of the universe as stated in the Tome of Nature.
