Fudge Flies were a sweet sold at Honeydukes. Apparently, Scabbers the rat enjoyed them, since, during the party celebrating Gryffindor's victory in quidditch over Ravenclaw in February 1994, Ron Weasley announced that if his pet rat, Scabbers, had still been alive, he could have enjoyed some Fudge Flies, which were one of his favourite sweets. At the time, Ron incorrectly believed that Scabbers had been killed by Hermione Granger's cat, Crookshanks.
