Allegedly Free Game: It claimed to be free to play, with perks for subscribers. Of course, those perks included: the ability to venture out of Toontown Central and its three streets, to learn more than the first four levels of Gags (attacks) of the two starting Gag tracks, buy clothes for your Toon and furniture for your house (among other things) from Clarabelle's Cattlelog, play games other than the few Mini Games in the first Playground, buy items for friends, and so on. It later got a lot better with this - free accounts allowed you to go anywhere (however, you can't buy anything outside of Toontown Central), use Speedchat Plus, buy from the Cattlelog and have up to 50 friends. Unfortunately, free users couldn't go into Cog Buildings or buy stuff outside Toontown Central. Then, when Toontown was closing, all Toons could buy stuff, go on missions to all the areas, fight Cog bosses and wear items. And now that Toontown is being reopened by fans, it's free to play... FOREVER.
Always Accurate Attack: There are S.O.S. Toons who can make it so that the next round of the Toons' attacks hit. There is also an inverse where some S.O.S. Toons make it so that the next round of Cogs' attacks miss.
Trap gags, if nobody can use a lure gag to trap the Cog into the trap gag.
The entire Drop Track. While they are second only to Trap Gags in terms of damage done, they have the lowest base accuracy of any gag track. Unless you have a friend who is simultaneously training Squirt Gags (very high accuracy), you're gonna be gag camping for a looooong time.
Bad Boss: Bossbots. You can even use their Pink Slips to fire Cogs.
Ballroom Blitz: Not necessarily a ballroom, but the C.E.O. battle is supposed to be a sophisticated and well-mannered meeting about golf or plotting the toons' defeat. Until you sabotage his plans by making the guests explode with bad drinks...
Boss Arena Idiocy: The Bossbot C.E.O. has seltzer bottles Toons can use to damage him, conveyer belts with treats on them for Toon-Ups, and golf balls they can use to slow him down.
Breakingthe Fourth Wall: One of a Legal Eagle's sayings when it uses the attack "Legalese" is "The opinions of this attack are not those of Disney's Toontown Online."
Bribing Your Way to Victory: Parodied with the Cashbot Promotion track. Once you have the Cashbot Disguise, you have to get a certain number of Cogbucks (by beating Cashbots or taking over the Mints) to see the C.F.O. for a "promotion" (aka fighting him).
The lure gag track consists of fake cogbucks used to make cogs come closer to the user For Massive Damage if you want to use another gag or to leading them into a trap or to temporarily stun them.
But Thou Must: Not only do you have to do all of the non "Just for Fun" Tasks in each Playground before the game sends you to the next one, there are several points in the game where it's very easy to end up in a Playground with only a single, very difficult Task, unable to proceed. The first obvious spot would probably be Daisy Gardens where you have to get a key from a Cog species found only inside buildings, but the exact Cogs you face in each building is random, and that species is quite rare at the levels of the Toons that would be going for the Key.
Chekhov's Gun/Hobby: When you play the minigames, there is one minigame where you have to shoot yourself out of the cannon and aim yourself into a big tub of water. Later in the game, when you fight the CJ, guess what you have to use?
Similarly, the 'treasures' that heal you in the main playgrounds reappear in the CFO battle and the golf course in Chip n' Dale's acres reappear in the CEO battle.
Chokepoint Geography: If you don't have teleport access to an area in Toontown, you can only get through there by walking.
Same with the Cog Headquarters, since you can't get teleport access there.
City Noir: The Lawbot Headquarters is surrounded by one. A popular fan theory is that the city is the location of Cog Nation.
Color-Coded for Your Convenience: The four types of Cogs have distinct logos and clothing colors that you can easily tell apart. About the only way you can tell a Short Change from a Cold Caller at a distance (see Palette Swap below).
Combat Medic: In most boss battles, there will usually be one person who has stocked up on a lot of Toon-Up gags or Toon-Up and/or Gag-Up phrases to help.
Damn You, Muscle Memory: Toontown has a relatively unusual control scheme. Movement is arrow keys only (as opposed to arrow keys or the WASD keys in some other games), and you don't press any specific key to start chatting, just start typing. If you've been away from the game for a while, you may end up typing long strings of characters when you're trying to walk around. Jumping is also different, with the Ctrl key instead of spacebar.
Dance Party Ending: When a battle finishes, the surviving Toons dance while gag experience and Toontask updates are completed.
Extended Gameplay: Beating all the toontasks in the Toon neighborhoods unlocks the Cashbot suit toontasks. Beating that unlocks the Lawbot suit toontasks. Beating that unlocks the Bossbot suit toontasks. Beating that unlocks quite a few "Just for Fun!" toontasks
Fake Longevity: The "Just for Fun!" toontasks allowed Toontown to create more time with the game without making new levels.
As well as the ever-known maxing out cog suits/gardening/racing/fishing.
You also get a real one when you maximize certain stats, such as once for every gag track you complete and one for maximum gardening shovel points.
Fishing Minigame: There's a fishing pond in every Playground and on every Street. There's Fishing BINGO every Wednesday, sometimes you have to fish for a Toon Task's objectives, and sometimes you fish just because it's one of the most lucrative methods of gaining Jellybeans.
Four Is Death: There are 4 kinds of cogs; Bossbots, Lawbots, Sellbots, and Cashbots.
Level Grinding: Required for most of the higher-level stuff. Gag "camping" is one of the most common, where you fill up with just one or two types of gags, and go hunt lower-level street Cogs to get experience.
Gardening is the most annoying, because you can only pick a flower once a day, and there's only ten flowers you can plant at a time. Worse, even the max-level flowers only give you one point per flower, requiring over a month of real time to level from 7- to 8-bean flowers.
Mass Monster Slaughter Sidequest: Toontasks in general, though the type of Cog in question usually varies.
The Maze: The Maze Game. The first stage of the Cog field office buildings involves a maze mini-game where players have to throw water balloons at the Cogs walking around to recover jokes and unlock the exit. The more jokes recovered, the more health restored when you do reach the exit.
Nightmarish Factory / Polluted Wasteland: The Sellbots own a factory where they manufacture other Sellbots, which also doubles as their headquarters. It is surrounded by huge rubbish dumps, the ground is covered in oil slicks and the air is clogged with smoke.
One-Man Army: With all of this game's focus on teamwork and friendship, you would not expect something like this. However, if you know what you're doing, along with going to collect the necessary equipment, your toon could become this anywhere in the game. Just ask this guy.
Retcon: The original backstory in the beta ties the game loosely down to the DuckTales universe in which the cogs are Gyro Gearloose's creation under the order of Uncle Scrooge, who accidentally activate the cogs when they're still not ready, causing an A.I. Is a Crapshoot scenario which they start replicating themselves out of control and taking over ToonTown. Disney executives apparently didn't like that and the backstory was retconned upon public release so that the Cogs just show up from out of nowhere one day and began invading ToonTown.
Scenery Gorn: The Sellbot Headquarters, which is themed after an industrial wasteland, with smog-choked skies, huge rubbish dumps that could also be mountains, gravel everywhere and oil slicks on the ground, too.
Screw This, I'm Out of Here!: The VP tries this after his first round of Cogs are defeated. Realizing that the Toons insist on pursuing him and that the elevator isn't opening, he decides to continue fighting.
The CFO also does this when he realizes that he's losing the battle with the toons. He is promptly run over by a train while trying to escape.
The CJ just retires to his chambers after the Toons win the trial and schedules a new one.
Soft Water: The final Toon-Up gag is a high dive into a cup of water.
Smashing Hallway Traps of Doom: Many of the Cog Headquarters have these, most notably the Sellbot factory which has an area that is quite literally the definition of this trope.
Spiteful A.I.: In the Cog Thief minigame, the cogs try to steal barrels that contain gags, and you try to throw pies at them to make them explode. If they hit you, they explode and you fly into the air. When this happens, the cogs currently on screen will turn away from the money and try to run into you, even though they will instantly explode upon running into you.
Two-Faced: Obviously, the Two Faces and Double Talkers.
Uncanceled: Ever since Toontown's closure was announced, fans have taken matters into their own hands and are private servers by going the distance to completely reverse-engineer the client. Toontown Rewritten and Toontown Infinite are two of the most popular private servers (but don't bring one up at the forums of the otherunless you're looking for a ban), although smaller closed-community servers also exists. Toontown fan sites and forums continue to remain active as well.
