A LOT depends on just how Toons are created, what their physical properties are, and what limitations there might be on what they can do. I’ve never read the original novel “Who Censored Roger Rabbit”, so I don’t know if that goes into the how of it. The movie doesn’t really touch on the subject except incidentally; it simply starts from the fantasy premise that animated cartoon characters exist in the real world and “cartoons” are just Toons being filmed like live actors.
From the movie alone, we can read between the lines and infer the following:[ul][li]Toons are created (or embodied?) by humans, they wouldn’t exist without us.[/li][li]They’re physically made, somehow, of ink and paint. They’ll dissolve in Dip, a mixture of turpentine, benzine and acetone.[/li][li]Except for Dip, they’re virtually indestructible (or at least can instantly regenerate from almost any level of damage).[/li][li]They are looked down upon and segregated from human society. Hollywood California is one of the few places in the world you’ll find them in great numbers.[/li][li]Many, if not most Toons behave in an abberent manner by human standards.[/li]Outside the film industry, they have limited utility.[/ul]I can only hypothesize that Toons are somehow outside the bounds of normal physical reality. They’re like solidified fantasies or hallucinations. Whatever the Toon creation process is, it must have extremely limiting drawbacks.
