Perfecto Prep is a preparatory school in Tiny Toon Adventures. It serves as a sporting rival to Acme Looniversity in the Wacky World of Sports shorts and other miscellaneous sporting events. Its other main use is personal rivalry between alumni of Perfecto, known as "Perfectoids" and alumni of Acme Looniversity.
Perfecto Prep is exclusive and high-brow and, with the exception of Montana Max, it is the school of choice for the more affluent toons. A hot-bed of snobbery and superiority issues, Perfecto's school motto is "we never lose". True to the motto, many students resort to cheating and bribery in an attempt to win events like the Acme Bowl, but their efforts always end in failure. Acme Looniversity is hated by Perfecto Prep, and many call those who attend it "Acme Loo-sers". There is a sense of Perfecto being desirable amongst certain Tiny Toons. In the short "The Amazing Three," Babs Bunny, Shirley the Loon and Fifi Le Fume go to great lengths to crash a sophisticated ball the school is holding.
Many students from both schools appear to be a mirror of one another. Roderick and Rhubella Rat (or Ruby), the most often encountered characters, are nasty alter egos of Buster and Babs Bunny. The two couples often clash over the rats' obnoxious and unfair behaviour and the rabbits take delight in teasing and pestering them. Other lesser seen characters, such as Danforth Drake and Margot Mallard, are parallel versions of Plucky Duck and Shirley the Loon. Later in the series, Shirley enounters a flock of beautiful but vicious Perfecto swans in the short Loon Lake. Only the ringleader, Giselle, is named. Other unnamed Perfecto characters include a male horse, a variety of rats and ducks, male and female hippos and a cow.
Nearly all of the Perfectoids are parodies of early 1990s "preppy" teen characters seen in contemporary shows like The Fresh Prince of Bel Air. As such, they have seemingly inexhaustible funds, opulent school facilties such as a hot tub and the attitude that success and happiness can be bought. They are usually not seen as evil characters, just highly unpleasant ones.
