Comic Book

Back in the 1950s, there was a whole line of comic books designed to scare children with the horrors of what was inside a toontown. Here's a panel from issue #4 of Cartoon Crimes. Benny the Fox is a regular member of the Fortunate Foxes and is frequently found enforcing various contracts. He's one toon that doesn't mind getting his gloves dirty.

Another Silver Age comic discussing the dangers of toonification and how morally wrong it was.
