Why is the airstrip out on its own little island off the coast of the main island? It's a bit of a hassle to land in a plane only to have to take a boat trip as well...
Have you seen Isle Delfino? There's no place to land a plane on the whole island. Presumably, the landing strip was added in once they became popular.
Truth in Television, sort of. Venice's Marco Polo International Airport is a bus and short boat trip away from Venice.
In fact, most airports are a good distance away from the cities they're associated with, for the simple reason that, well, you need a lot of room to land a plane safely, and a lot more room to make sure you have a buffer just in case things go wrong. When This Troper went throughout Europe, nearly every airport he landed in was a solid hour drive or more away from the city the airport was nominally in.
Not to mention planes are really freaking loud, which is why property values near airports are so low.
Why do the Yoshis dissolve when they touch water? Are they made of water soluble paint? And isn't it stupid that out of all the species of Yoshi in the world, it would be the island-dwelling ones who would be unable to swim?
A group of Yoshis got to the island a long time ago, and in later generations, they never learned how to swim. As for the dissolving thing, I got nothing.
Aren't most Yoshi island dwellers? It could be that they aren't real Yoshis. Since a large part of the plot was someone painting on the island, is it really out of the question that the Yoshis are also just painted things that Bowser Jr. created because he was trying to imitate one of his father's schemes?
There's a Noki woman with a baby standing outside of Pinna Park. The weird part is, when you talk to her, she never once suggests that it's her kid or if she's related to it at all, referring to it as "the child" and "this baby." Did she kidnap it? Is she babysitting it? Is she just really detached? It's a small detail to get hung up on, granted, but it still bugs me. (You see her again later in Noki Bay, but I can't remember if she says anything more revealing then or not. I don't think she does, but...)
Maybe she thinks Mario's smart enough to fill in the blanks. Maybe she just talks weird. Maybe Mario doesn't need to know every detail about her life.
I think the Japanese version for "this child" (この子) and related is common in that language for referring to one's child, and they just made the translation pretty literal.
I think seeing Mario go the extra mile convinced the inhabitants that Mario is a good man. He only needed 50 Shine Sprites to restore Isle Delfino, but he tracked down all of the missing Shine Sprites anyway. Most of those, I'd bet, were not even stolen by Bowser.
How come no one ever questions what the two Racoons/Tanukis are doing charging Blue Coins in order to get Shine Sprites? I mean, the whole reason there's darkness over Isle Delfino is because the Shine Sprites fled when the pollution started and they're basically needed in order to restore the Island to what it once was. How come the two racoons/tanuki are allowed to withhold something that is that vital to the island and sell them without anyone ever questioning them or taking actions against what they're doing, especially since Isle Delfino is in danger? I even watched Chuggaconroy's Let's Play of the game and even he questioned this.
That explains why the people would hold onto them, but not why the authorities don't do anything about it. I mean, Mario pretty much had to face a Kangaroo Court at the start of the game, yet the government doesn't respond with the same heavy-handedness to the people who are hoarding Shines. And the police would presumably know about their importance, since the prosecutor did, and D.E.B.S. does, and one would think the police would have access to D.E.B.S....
In the intro, the Pianta mumbles something twice: Once at the beginning (after saying, "Welcome to the sun-drenched paradise of Isle Delfino!") and again at the very end of the video. What is he saying, and why is he mumbling it?
I've heard it too, and it seems to be just some kind of chant. Maybe it's akin to saying "Aloha" if it were an ad for Hawaii.
The Delfino Plaza flooding makes absolutely no sense. Even if all that water was indeed inside Corona Mountain (which already raises several questions, being a volcano and all), once being released, it would have immediately fallen into the sea, thus making it impossible to flood anything. To flood a city surrounded by mountains, in a low area, you only need to pour enough water over it, since the geography will hold the water in place. To flood a whole island, you need to raise the sea level several metres, so it covers the island. And since the sea level is the same everywhere, you need to release enough water to cover the entire world- or else the water will immediately spread through the sea all over the globe, making the rise unnoticeable. Can Corona Mountain hold that much water? Really? And then, after defeating Bowser, the flood disappears in a matter of seconds...
Either the island is much bigger canonically than it is depicted in game which would make it so the flood would take some time to escape the city and go out to sea, or Magic.
Maybe the water is held in place by the ridiculous magical barriers that prevent you from swimming too far away from the island.
So Shine Sprites are the guardians of Isle Delfino's light. If the Pianta are aware of the Shine Sprite's importance to the island, why are they holding contests with the prize being Shine Sprites (a good example being the watermelon-growing contest)? Shouldn't they be more considerate - giving up the Shine Sprite so light can be restored? Shouldn't there be some government officials sent to retrieve them for that matter? Remember, Mario was only tasked with cleaning the island, not retrieving the Shine Sprites.
I have a question about Sirena Beach's hotel. First, why would a 4-star hotel like this have secret passages, like the one that takes you from the men's room to a woman's bathtub? I know it's standard platformer game physics, but what are those passages doing there in the first place?
Maybe all the ghosts made them. At least a few of them, like the Boo painting, are ghost intervention.
What are the purpose of those caged platforms around the pirate ships at Pinna Park? They serve no apparent purpose, visual or mechanical. Why are they there?
Reason: Maintenance. they are there in case workers need to make repairs to the ride.
Why, after being revealed, does Bowser Jr. still use his Shadow Mario disguise at all? I can understand that it'd be a definite spoiler if someone say, got to the levels where FLUDD is stolen or they have to chase Shadow Mario in the 7th episodes of one of the earlier levels before getting the 10 shine sprites required to get to Pinna Park, then yeah he should still wear the disguise as the cutscene hasn't played yet showing who he really is. But why bother after Pinna Park? Mario has been framed as much as he could manage by then, he has been seen by various people being chased by Mario before then in his disguise thus nullifying its use for further framing of Mario. But he still uses the disguise for seemingly no reason. When he is running around with parts for FLUDD he is still disguised. In the chase missions after the reveal he is still in disguise. Even when he is being chased for the Yoshi egg which only happens after clearing the first four missions of the level his disguise is removed in, he is still posing as Shadow Mario. And even for the people who have yet to see Mario chase after him before, during the chases after he tried to get Peach the first time, he doesn't even bother drawing his graffiti M's on the ground when he stops. So what's the point?
Maybe Bowser Jr. just wants to make sure that nobody knows who he is (except Mario, but nobody on the island listens to him anyway), so that people won't notice a pair of Koopas running around the island causing trouble. The residents already have difficulty telling Mario apart from Shadow Mario, but they'd probably notice Jr. in his regular form. If he got caught, he'd call attention to himself and it would put a damper on the vacation his dad planned. I know that Bowser could just do what he wanted anyway, given that he's Bowser, but maybe he was willing to (sorta) play by the rules to have a good time. Aside from kidnapping Peach, all really he does is go hot tubbing in Corona Mountain, so he was probably just personally aiming to kidnap Peach and piss off Mario, while letting Jr. do whatever he saw fit to get in Mario's way as long as he didn't get framed for it (ex. gooping up the island).
It could be that the Shadow Mario disguise is what lets him use Mario's moves. Without them, it wouldn't be hard for Mario to catch Junior.
It always bothered me that during the court scene, the judge just overrules Peach's objection without even hearing it. We're talking about a Princess here. Royalty. If Delfino is part of the Mushroom Kingdom, then he's basically telling the ruler to shut her trap. If Delfino is not part of the Mushroom Kingdom, then that attitude is just asking for a diplomatic disaster.
