Armadillo

• Type: Creature, Potion Ingredient Source
• Notable Products: Armadillo Bile
• Patronus Form: Yes (Pottermore)

An armadillo is a small Muggle mammal known for its distinctive leathery armored shell. The books do not provide a separate magical description, implying that the armadillos used in the wizarding world are the same as their non-magical counterparts. Their primary defense mechanism is to roll into a ball, allowing their tough exterior to protect them from predators.

While the creature itself is not described as having innate magical abilities, its biological products are utilized in potion-making.

• Potions: The bile of an armadillo is a known potion ingredient. It is specifically listed as a component of the Wit-Sharpening Potion, a brew designed to enhance the drinker's clarity of thought. In her second year, Hermione Granger purchased Armadillo Bile from the Apothecary in Diagon Alley.
• Patronus Charm: The armadillo is a possible corporeal form of the Patronus Charm. This suggests that the creature is associated with positive feelings and possesses qualities, such as protection and resilience, that align with the nature of the Patronus Charm.

• In Harry Potter and the Chamber of Secrets, when Harry Potter and the Weasley family are shopping in Diagon Alley, Hermione Granger meets them and mentions she was at the Apothecary purchasing ingredients, including Armadillo Bile.
• In Harry Potter and the Order of the Phoenix, the armadillo is mentioned in a conversation between Kingsley Shacklebolt and Arthur Weasley. When discussing how Arthur would send a warning message via Patronus, Kingsley asks, “An armadillo?”, mistaking the form of Arthur's Patronus. Arthur corrects him, stating his Patronus is a weasel.

• The armadillo is one of the many possible corporeal forms a witch or wizard can produce when taking the official Patronus Charm quiz on the Wizarding World website, formerly known as Pottermore. (Pottermore)
