The library fiends reside in the library at Mu Elementary School and eat all the books. In the web episode "Rainy Day Schedule", they were called "noise-making fiends" and were not library fiends. Then, they were used to annoy the schoolchildren on rainy days. In that episode, Charlotte befriended them by giving them bubble gum, Charlotte believed they were puppies, They made another appearance in "Marvin the Middle Manager", when they ate Marvin's instruction manual.
