Shirley McLoon

Shirley "the Loon" McLoon, a young female loon, is a citizen of Acme Acres featured in Tiny Toon Adventures.

Shirley is one of the few characters of the show not directly inspired by an existing Looney Tunes character. She speaks with a thick Valley girl accent and, although she seems reasonably intelligent, is obsessed with superficial New Age paraphernalia. Her name is derived from fellow New Age aficionado Shirley MacLaine, while the latter part of the name is an obvious pun. She appeared in an episode of Animaniacs next to MacLaine. More often than not, characters refer to Shirley as "Shirley the Loon" rather than "Shirley McLoon." She appears not to notice the negative connotations of the nickname, and, in fact, the mantra she recites while meditating is "Oh, what a loon I am. Oh, I'm a loon." Shirley is often pursued romantically by Plucky Duck and Fowlmouth. When not meditating or fortune-telling, Shirley hangs out with her Acme Looniversity classmates Babs Bunny and Fifi La Fume. She also appears to be a skilled sorceress, as in one episode, she used her powers to give Plucky the IQ of Einstein to help him ace a test.

In "Love Disconnection", while attending a high school dance, Shirley gets doused with red punch (driving her into a tranquil fury as seen in the movie Carrie), then proceeds to flood the gym with her telekinetic powers.

Despite her annoyance with Plucky, Shirley does seem to care for him and does date him on occasion.

Shirley is a keen ballerina who has to face prejudice when attending an upmarket ballet school otherwise attended exclusively by Perfecto Prep swans. Jealous at her superior dance skills, they mock her accent and try to sabotage her performance at their recital, but are soon thwarted by Shirley's nimble moves and a behind-the-scenes Babs, staging a sabotage of her own.

Shirley is voiced by Gail Matthius.
