-The reason Gepetto never sold his clocks is because they were his life's work, made for his wife or his child. Sofia explains that he did that to get the dinghy to go to Pleasure Island in the first place, which shows how much he's willing to go for his wooden son.
-The Blue Fairy is indeed superfluous to this story, honestly she didn't even really need to appear to begin with. Just have it so the star still shines on Pinocchio, bringing him to life and have the cricket explain what's right and wrong.
-Sofia actually just uses the garbage to eat. Seagulls (and other members of the Laridae family for that matter) are very opportunistic and crafty creatures, often eating things that aren't meant for consumption. I once ate lunch near the water and a seagull literally swooped down, grabbed my empty milk carton and flew off to eat it before I could do anything about it.
-I'd argue she isn't ENTIRELY pointless, she's one of very few people this Pinocchio meets on his journey that has no ill intentions for the puppet, considering how much it happens in the Disney version and the original story. She at least has a sort of unique backstory where it's hinted that her leg was damaged either through abuse or an accident, preventing her from becoming a ballerina. I at least thought the brace was interesting, just goes to show how far prosthetics have come.
-She actually TRIED to get the key for Pinocchio, but because Stromboli barged in she had to flee, leaving the latch open for him to close later.
-I wanted them to say that line so bad, you don't even know Mr. Panda. What good is adapting a historically significant fable like Pinocchio and not using it for the moral that made it famous?
- I dunno, if my head was made out of pine and I was discriminated against by the one person (the schoolmaster) I was told to follow, why wouldn't I eventually end up at pleasure island? In this version the urchins (and yes, they're clearly intended to be street urchins) state that they've been swept up off the street after dark, and that Pinocchio should know this. This implies that it's sort of an established "cautionary tale in a cautionary tale" like how the boogeyman was created to discourage bad behavior or fairy tales scaring kids from running away into the forest. Geppetto likely put two and two together and knew that's where he'd end up.
Playing pool, while not an inherent sin can be attributed to gambling, as bets can be made on it. It's a bit of a stretch but the fact that they did this in a bar (adult bar, not the traditional Italian bars) makes the implication that him merely being there would result in him transforming into a donkey regardless, and it seems bad behavior accelerates the process compared to the original. Do have to give them credit though for making Pinoch's donkey ears and tail made out of felt and wood respectively, that was a nice touch.
- Stromboli actually was largely responsible for underpaying his employees and making a hostile work environment, Fabiana reveals this to Pinocchio when he's trapped in the cage. Kind of shocking considering how the original film had most of it's antagonists get off scot free (for the most part).
- Not going to lie, I really wanted them to do the underwater walk like the original, but I guess it's hard to do because everything is realistic (Remember, they're not cartoons anymore, Pinoch is a REAL wooden puppet and Jiminy is a cricket with all of the abilities and limited air of a cricket). It's a shame because with how detailed most underwater scenes have gotten (KH's Caribbean comes to mind, that manta is fantastic) it would've been nice to see native fauna of the Italian penninsula's oceans in a Disney movie.
-Well, I'd argue this is kind of closer to the original story, as in Collodi's version Geppetto and Pinoch are swallowed by
"il
Terribile Pesce-cane" (or the terrible dogfish in english). A dogfish is a type of shark, and while this Monstro is still more whale inspired, it's more streamlined and sleeker than the original. I guess it's intended to be like the sea monsters that were put on old maps back in the day, possessing a lot of parts from known marine life (octopus tentacles, a whale's blowhole, a shark's dorsal fin) but honestly they could've just went the King Louie route and made Monstro an extremely large basilosaurus, at least then it'd be more whale-like.
-Well, Pinocchio needs to have some moves when he's a part of the party in KH IV when Sora visits the world. It'll be called piede di fuoco and it uses up all of his MP. Don't worry, I got this information from a reliable source, I know what I'm talking about
I guess Disney really wanted to pull a Porco Rosso ending, they were on a beach.
