Giant Purple Toads have the ability to stun a human whenever disturbed, and are particularly vulnerable to the Verdimillious Charm spell and resistant to the Fire-Making Spell. Its warts (which can be removed with a Knockback Jinx) are used in the Dragon Tonic . Having warts removed annoys them, though, and they disappear into another hideout to spite the wizard who needs the warts. Giant Purple Toads and their warts are sold at the Magical Menagerie.
