These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Toontown Online
Broken Base: Between the two most prominent private servers, Toontown Rewritten and Toontown Infinite, to the point where TTR members are not allowed to mention Infinite on the official forums.
Ear Worm: Most of the themes are catchy and fun, like the game implies. Heck, even the boss battles sound great!
Game Breaker: The most common way of beating high-level Cogs is by having two or three Toons use a Fog Horn Sound gag, and having the remaining Toons use an Elephant Trunk. This has the capacity to destroy full teams of level 11 or 12 Cogs (depending on how many Fog Horns). Toons can take turns using either gag, allowing them to destroy waves of Cogs with no effort and even less thought.
Imagine living in a world where random robots just started to come over and destroyed our way of life as we know it.
The various music for Bossbot HQ and the theme of it. Going to Bossbot HQ late at night when it's dark out is enough to give someone the chills. (Especially if you're the only person there).
Skelecogs can fall under this trope too. Not only do they look quite eerie, but their distorted voices that sound much more robotic than the normal cog voice alone is probably enough to give the younger players of the game nightmares.
The Downsizer trading card, which depicts him painfully shrinking a captive Toon while the Toon's friend watches in horror.
Promoted Fanboy: All the fans who are working to develop Toontown Rewritten and Toontown Infinite.
Rescued from the Scrappy Heap: While being The Scrappy for being That One Boss, Lil Old Man can also show up as an SOS Card from the Sellbot VP. He performs extremely accurate Hypno-Goggles, which can come very handy if a Toon or a team of Toons really need a Lure, badly.
The NPCs who hand out Toon Tasks that require you to defeat innumerable amounts of high-level cogs and buildings are positively loathed by both newbies and experienced players alike. However, Lil Old Man stands out amongst them all of them as the biggest Scrappy, whose Toon Tasks are nothing butScrappy Levels by the time you see him again. Even his SOS card doesn't completely save him from the hatedom.
Cleff in Minnie's Melodyland also gets his share of hatred. Why? He requests you to deliver a whole cream pie, a gag which you are very likely still extremely far off from getting by the time you reach him (as in, most aren't even halfway done training for it!). This essentially forces you to level grind for the pie and it wastes a space on your toontasks until you finally reach it, probably around the time you're ready to start your last toontask for the neighborhood.
Lil Old Man. The first time you meet him, he's not so bad. The second time...He gives you 20 4+ story buildings to do. Better get to it!
From the trolley:
Jungle Vines, which has incredibly stiff and awkward controls, and judging where you will jump is a pain and a half. Also, if you're facing somebody who is better than you, you might as well just shut off the game — they'll take all the bananas away from you without a hitch.
Photo Fun takes forever to play properly, and the reward is not worth it. It also takes forever waiting for toons to get in their proper pose. Most people outright skip this one by wasting their film as fast as possible.
