Elmyra Jessica Duff is the secondary antagonist from Tiny Toon Adventures, voiced by Cree Summer. She is a young, overly affectionate 12 year old, red-headed, female human with a light blue short-sleeved blouse with a white collar and frilly cuffs; a matching bowed ribbon in her hair that has an animal's skull in the middle; white pleated knee-length skirt; frilly light blue (with or with out red hearts), pink or white panties; matching training bra; white ankle-length socks and black Mary-Jane shoes. She lives in Acme Acres and as in the original series, attended Acme Looniversity. She is based superficially on her name derivative and mentor, Elmer Fudd, but her personality is more like that of Hugo, the Abominable Snowman.
Whereas Elmer was a hunter who usually tried to kill Bugs Bunny or Daffy Duck, Elmyra is obsessed with animals and cute things, but always causes great discomfort or serious injury to potential pets from her overenthusiastic affection and complete lack of even the most rudimentary knowledge of pet care. She is very similar to Mindy on Animaniacs. Elmyra made a guest appearance on Animaniacs in the segment "Lookit the Fuzzyheads", where it was revealed she was another one of Dr. Scratchansniff's patients. Mistaking Yakko, Wakko, and Dot for puppies, she chased them around until the Warners tricked her into chasing after Mindy instead (and saving Buttons the trouble of doing so himself). She also made cameos in "The Warners 65th Anniversary Special" and "A Hard Day's Warners".
However, Elmyra's most prominent connection with Animaniacs was starring alongside Pinky and The Brain in the infamous spin-off Pinky, Elmyra and the Brain. In the theme song to that series, Elmyra ends up buying the two mice along with a turtle named Mr. Shellbutt while they were trying to hide out from Wally Faust. Unlike in Tiny Toons, Elmyra now attends Chuck Norris Grammar School and now has a crush on Rudy Mookich (it is never mentioned what happened to her old crush, Montana Max).
