The Knarl is a creature that greatly resembles a hedgehog, so much so that there is only one known (behavioural) difference between them: when food is left out for a hedgehog it will appreciate and enjoy the gift; a knarl will see it as an attempt to lure it into a trap and hence savage the garden of the householder who left the food. Muggle children have often been blamed for damage committed by a Knarl.


They were featured in the Care of Magical Creatures O.W.L. during the 1995–1996 school year, where students had to locate it amongst a group of hedgehogs. The trick was to offer each creature some milk.

Knarl quills have magical uses. Fred and George Weasley once paid Mundungus Fletcher six Sickles for a bag of knarl quills, to experiment with for possible use in their Weasleys' Wizard Wheezes products.[1]

Knarls eat wild daisies. A potioneer will often have to remove Knarls from a daisy patch in order to pick the flowers. Casting a well-aimed Stunning Spell at the Knarl will work well and will not do any permanent harm to the animal.[2]
