Fan Casting Animaniacs: The Not-So Grand Discovery

After finding a way out of the water tower that they had been locked in since the 1940’s, The Warner Brothers (and the Warner Sister) have been running amok, but they soon find another toon named Discovery, who claims to be the Fourth Warner Sibling. But Wakko notes that there is something odd about Discovery, and all the while, the current CEO’s of Warner Bros, Will and Wendell have been making some…. idiotic decisions, with the sinister Baron Doom lingering in close proximity.
