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.
In "Don't Ask Muffy," Buster imagines himself going there to find info on how to be a comedian. He imagines the dry cleaners worker working there. It is unknown if she actually does work at the store, or if he only imagined a random person doing so.
