The series centers on a group of young cartoon characters who attend a school called Acme Looniversity to be the next generation of Looney Tunes characters. Most of the Tiny Toons characters were designed to resemble younger versions of Warner Bros. ‘ most popular Looney Tunes animal characters by exhibiting similar traits and looks. The two main characters are both rabbits: Buster Bunny, a blue male rabbit, and Babs Bunny, a pink female rabbit not related to Buster, Plucky Duck, a green male duck, Hamton J. Pig, a pink male pig. Other major characters in the cast are generally nonhuman as well. These include Fifi La Fume, a purple-and-white female skunk; Shirley The Loon, a white female loon; Dizzy Devil, a purple tasmanian devil; Furrball, a blue cat; Sweetie Pie, a pink canary; Calamity Coyote, a bluish-gray coyote; Little Beeper, a red-orange roadrunner; and Gogo Dodo, a zany green dodo. Two human characters, Montana Max and Elmyra Duff, are regarded as the main villains of the series and also are students of Acme Looniversity. As villains, Elmyra is seen as an extreme pet lover while Montana Max is a spoiled rich brat who either owns lots of toys or polluting factories. Supporting characters included Li’l Sneezer, a gray mouse with powerful sneezes; Concord Condor, a purple condor; Byron Basset, a usually sleeping basset hound; Bookworm, a green worm with glasses; Arnold the Pit Bull, a muscular white pit bull; Fowlmouth, a white rooster with horrid language; Barky Marky, a brown dog, and Mary Melody, a young African American human girl.
