Lynts

Lynts are an infectious species of critters that inhabit Hats of Holding. They appear as small, fuzzy black spheres with two yellow eyes and vicious teeth. They infest Hats of Holding, but can be deterred by annual cleanings. Lynts have a queen, although beyond that their heirarchy is unknown. Lynts appear to be carnivorous.

Appearance
Lynts are fuzzy black spheres, their only features being two glowing yellow eyes and a huge fanged mouth. Their mouth takes up most of their body, to the point where opening it vastly changes their shape. Their jaws can open extraordinarily wide, which they use to bite larger prey.

Queen Lynts are of much larger size, and a different shape entirely. They appear more similar to a squid, with a huge, long black body covered in hair and a mass of tentacles at their bottom. They can have over ten eyes, and their teeth grow much larger and more protruding.

In-Series
In Volume 8, Gertrude enters Larry's Hat of Holding in order to retrieve a catastrophon. While in there, she discovers an infestation of lynts, which she battle with the help of various beings accidentally imprisoned inside the hat. After slaughtering hundreds of lynts, Gertrude does battle against a queen, which eats her box loader. Gertrude is almost killed before the stray catastrophon devours the queen in seconds.

Trivia

 * Lynt is a play on the word lint, which gathers in uncleaned hats.
 * Lynts have bones, as shown by the devoured remains of the queen lynt.
