A runaway Toon seems to have had slipped on a banana peel while racing and caused a bit of a ruckus! Luckily, there is probably some form of edit tool that can clean things up. Remember to avoid plagiarism when editing.
Cannons are used for many things in Toontown Rewritten. They are used in Cannon Game, during the jury round in the Chief Justice battle, and can be rented for the Toon's estate. Unlike all the other cannons, the cannons purchasable for parties allow Toons to control their trajectory after they're fired out of them.
When using a Pink Slip on a Cog in battle, the Cog is fired out of a cannon.
Cannons were also used as one of the activities for ToonFest 2015.
