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.
Accidental Aesop: Walk with your kids to school to make sure they don't run off or get kidnapped by strangers.
Alas, Poor Scrappy: Lampwick may be a spoiled brat like the rest of the kids that come to Pleasure Island, but his ultimate fate is far beyond what he deserves.
Alternative Character Interpretation: The Coachman. A theory is that he's a karmic trickster, like an Anti-blue fairy (His coat is even red). While she has them learn from their misdeeds and sends them towards redemption, he punishes them for their stupidity and misdeeds by transforming them into donkeys. His nightmare face implies that he might be a supernatural creature, like the Blue fairy.
Awesome Music: The whole soundtrack can count, but special mention goes to "When You Wish Upon a Star". That one song was so good, it became Disney's de facto theme song. The song and score both won Oscars.
When the American Film Institute held a poll for the 100 greatest songs used in American films, "When You Wish Upon a Star" came in seventh place - higher than any other Disney song.
Complete Monster: The Coachman. Seemingly a kindly old gentleman, he lures a bunch of troublesome boys to an island where they can do whatever they want without adult supervision, and laces their cigars and beer with something that, when they act like jerks, turns them into donkeys he then sells as ordinary animals. From what he says to "Honest" John, he has been doing this for years, and the police have never caught him because by the time they arrive, the boys have already become donkeys, leaving no evidence that they were even there. The transformed boys who can still talk are locked up in a pen (it is unclear what becomes of them, though we're probably better off not knowing). Worst of all, he is a Karma Houdininote Although you do kick his ass in the SNES game of the same name..
Designated Villain: Monstro. He's classified as a villain since he deliberately tries to eat Pinocchio and Geppetto after they escape from inside him...but as the book "The Encyclopedia of Disney Characters" puts it, if someone lit a fire inside you, you probably wouldn't be very happy with them either.
Mean Character, Nice Actor: Monstro even guest-starred as a good guy in a Bonkers comic story. According to this comic, he is a well mannered but destructive (due to his size) Toon actor who has not had much work since this film.
Ho Yay: Like it or not, Pinocchio/Lampwick (a.k.a Pinocchwick) is becoming a rather popular ship. Oh and never mind that they are just little boys, the pair is spreading around slowly as we speak. Due to their ages, it also counts as Toy Ship.* But to be fair, those who tend to make "stories" about them are given age-ups to steer away from that forbidden zone.
There are people who notice their interactions in the film and they tend to point out the certain moments that screamed Opposites Attract, hence this pairing. Pinocchio clearly looks up to him and Lampwick seems to be enjoying the attention. Some like how his bad boy quality played off on Pinocchio's innocence. Make of that what you will. Oh, wait...never mind.
Tear Jerker: Pinocchio's apparent death. Also included should be the Adult Fear moment when Geppetto walks desperately through pouring rain in search of Pinocchio when he doesn't come from school. His increasingly desperate cries of "Pinocchio!" ringing out while his puppet-son is unknowingly being carted away just in front of him is pretty agonizing for anyone who's ever been in charge of the welfare of another.
Oddly, enough. you can't even help but feel sorry for Lampwick during the transformation scene. It's not a good view seeing him while he desperately gets down on his knees and begs Pinocchio and asking for Jiminy's help.
The Woobie: Geppetto. Seriously, he first desperately looks for his kid, then he get swallowed along Figaro and Cleo in the belly of a whale where he risks to die starving.
Pinocchio. The poor kid's naivety leads him to some really awful situations.
