Trident Books is a bookstore. It appeared in Prunella's Special Edition. It then appeared in various other episodes like Fern and Persimmony Glitchet where Fern and Francine were buying the new Horrendously Horrible Happenings book, and Sick as a Dog, in the opening when Arthur is walking Pal. Max Wheeler was there that day to autograph books in place of Persimmony Glitchet. Trident books.jpg|Book signing. Tridentbooksimagination.png Trident.png|Trident Books in Sick as a Dog.
