A bookworm from The Library.


Coming from the Library, Lexicovermus is a green bookworm wearing glasses, a tie and a graduation hat. He pops out of nowhere in just about anyzone from a book. The hole in the book is like a wormhole from where he can pull out other items. When going away, the book closes and disappears with an audible "POP".

Naturally, Lexicovermus is both literally and figuratively a bookworm, and he likes recommending others to read. He does so with the commenters in Awful Hospital, breaking the fourth wall. He even used to be found in the webcomic's library, greeting the reader. Fern occasionally finds him but he completely ignores her, only talking to the readers and offers to show Fern one content from the webcomic's library chosen by popular demand.

He mentions the word "lexicomorphosis", which might be the process of transforming someone into a book. Judging by the writing on the book he comes out of, the book seems to have been once a human now transformed into a series of books and can even feel the Professor eating through it. Interestingly, the victim recalls having a professor back home that had the same voice as Lexicovermus. It can be speculated that Lexicovermus was disguised as a grey zoner and punished someone who didn't like books.
