Elmyra Duff is based superficially on her name derivative and mentor, Elmer Fudd; "Elmyra" being a female form of "Elmer" and her last name, "Duff," as "Fudd" pronounced backwards. According to creator, Tom Ruegger, she also got her first name from his next door neighbor in Northridge, CA; an elderly lady named Elmyra Lamb. Elmyra strongly resembles a younger version of the feminized Elmer Fudd from the 1946 cartoon, The Big Snooze, in which Elmer's peaceful retirement dream became a nightmare where he was transformed into a shapely female by Bugs Bunny. She behaves quite a bit like Little Suzie, a child from a fairly obscure 1955 Freleng short called A Kiddie's Kitty. Here a girl adopts Sylvester Pussycat and unwittingly abuses him with her childish antics, to the point that he decides he would rather take his chances with a bulldog who had been tormenting him earlier in the picture.
