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.
Fridge Horror: The game heavily implies the bad path was taken for several events in the first game, including Moody having amnesia from an unmentioned incident and the telephone referencing Prescott taking it apart.
The opening outright shows us that he took the thinner path for The Clocktower fight. And since the small shadow blot is only ever referred to as beaten but never actually seen by the player, we can assume he took the thinner path for that one. Which might be understandable, since unlike all the other enemies Mickey didn't have any idea that it could be redeemed and thought it was an embodiment of evil throughout the game.
We're told that Captain Hook is alive but currently missing and we even re-meet Petetronic at some point in the game so we can rest a little easier knowing Mickey fallowed the Paint Path to some extent.
Happens to anyone who remembers Pete's Dragon and/or the old Main Street Electrical Parade - especially if they're taking the Thinner Path. The "Blotworx Dragon" boss is actually the parade's version of that movie's titular dragon, Elliot.
Harsher in Hindsight: While talking about how and why he signed up to direct the original Epic Mickey, Warren Spector reportedly said: "You know, this is probably impossible, we're probably going to fail. I'm in." Although the first game did pretty well for itself, the second one was such a financial bomb that Disney shut down Junction Point Studios.
The series' entire premise of a world for forgotten characters is now harsher in hindsight, since Junction Point being shut down means the characters are most likely going to be forgotten again (barring Oswald, who's getting some merchandise).
