Paige Turner (voiced by Katie Hutchinson) is the librarian in charge of the Elwood City Library (thus, her name is a pun). She is a rabbit who wears glasses and has numerous watches. Her hair color has changed from dark brown to light brown throughout the show's run. She is friendly, polite, and calm to library patrons. Nonetheless, a running gag is the widespread fear of her by library patrons due to worrying about their responsibilities with books and behaviors in the library. Mr. Walters is Fern's father. He appears much less frequently than Fern's mother and is first seen in the episode "Phony Fern", plus in the episode "Fernlets by Fern". He is a brown dog in a blue jacket. He teaches Fern about computers. Doria Walters is Fern's mother. She works for a real estate company. Her hair, which hides her ears, is a noticeably different style than Fern's. She has an outgoing personality and is very confident and encouraging to her daughter (who would prefer if she wasn't). Mrs. Wood is Perky's owner. Her grouchy dog, Perky (also known as "Jaws"), is Pal's mother. Guest stars Art Garfunkel appears in animation as a moose in two Arthur episodes: first in "The Ballad of Buster Baxter", and then later in "Elwood City Turns 100!" as one of the guests that Muffy invites to the play. Arthur Ganson appears in the episode "Muffy's Art Attack". The Backstreet Boys (Nick Carter, Howie Dorough, Brian Littrell, A.J. McLean, and Kevin Richardson) appear in the movie special "Arthur, It's Only Rock 'N' Roll". Click and Clack, The Tappet Brothers (Tom and Ray Magliozzi) appear in the episode "Pick a Car, Any Car", where Arthur calls them about the family car to save it from the junkyard. Matt Damon appears in the episode "The Making of Arthur" as the host of a show "Postcards from You" (inspired by the "Postcards from You" segment used as the mid-show feature on Arthur since Season 11 and the feature on the second season of Postcards from Buster). Édgar Rentería appears in the episode "The Curse of the Grebes" as Bateria, a member of the Elwood City Grebes.
