Nargle

The Nargle is creature that Luna Lovegood and Xenophilius Lovegood believe exists though not many others do. The Nargle is known to infest mistletoe and to be a mischievous thief. Luna Lovegood claims that her Butterbeer cork necklace keeps the Nargles away.

Luna Lovegood claims that her papers were taken by Nargles.

When Harry Potter and Cho Chang were about to kiss under the mistletoe, Harry jokes that Nargles may be infesting in it. Cho, who had never heard Luna discuss her belief in this creature, was confused, so Harry let the topic drop.
