Cannons function many things in Toontown Rewritten. They serve as one of the trolley games, Can
non Game, in which toons try to launch themselves into the target, which is a bucket of water. They can also be purchased at your estate for 1000 jellybeans for 2 days, in which toons hit numerous targets in the sky, and try to get laff from the big laff target. They are also used in the battle against the Chief Justice, in which toons launch themselves into 10 chairs, turning the cogs into toons for evidence.
