there's free revivals of the game! toontown corporate clash is the best one imo because it removes some of the grind and adds a ton of content, and toontown rewritten is a more faithful recreation of the original game that hasn't added much but is still very popular, they're still tons of fun today :D
i remember a bldg i did with my friends and all the cogs beside the boss were level 11 and there were so many of them. the final floor was infested and i was the only toon with lure ........
there's a floor in Roblox the normal elevator where the elevator stops in the final floor of cog building and where a boss named the big cheese go in the elevator, instead of attacking the player.
This was some day in the last month of Toontown. I can't remember the actual date. I just uploaded it when I had time which happened to be on Sep 17, 2013.
