* Why is it that the Thwomps, Whomps, and Tox Boxes can [[OneHitKill crush Mario stone dead with just one pound]] while Giant Bowser's punch does standard damage to Mario? You'd think his size should count for something.
** Have you seen those guys? The way they crush the ground, you'd think they were made of lead. Their attacks hit HARD (the Mario Party game "Cardiators" puts a Thwomp impact as the absolute strongest attack among major Mario enemies). But they're slow and predictable. Bowser himself can't hit as hard, but he's highly adaptable, can strategize on the fly, and can actually attack in more than one way and without a rhythm.
* How do the Piantas who live in that space island known as Starshine Beach Galaxy get food to eat?
** I'm guessing they live completely on the Dash Peppers and Blimp Fruit that grow there?
*** Seems kind of a pain to get blown up into a balloon after every meal.
*** Maybe the fruits only affect Yoshis?
** They also seem to lack any noticeable houses.
** They could also eat those crab enemies.
* ''VideoGame/SuperMarioGalaxy'' opens at the Star Festival, which happens every hundred years, right? And ''VideoGame/SuperMarioGalaxy2'' ... ''also'' opens at the Star Festival, which happens every hundred years? Are these GenerationXerox characters a hundred years later? Or is it still the ''same'' Star Festival, and Peach gets kidnapped by Bowser twice in the same night? (I haven't finished the first game yet, so if that provides some sort of explanation, apologies.)
** Mario and Co and immortal, duh.
** Wasn't the universe destroyed and recreated at the end of the first at's tegame? I'm thinking it was created a little younger than the original was destroyed.
*** Yeah, what the above poster said. I was under the impression that the end of ''Galaxy 1'' was a big ResetButton that threw Mario back to the point the game started from, with the exceptions of Bowser's attacking and the newly-formed Galaxy.
** ''"But the cycle never repeats itself in quite the same way...So...You'll see."'' That's why things were reset to how they were during the Star Festival, except with all the characters he'd met during the game attending, as well. (There's also a bit of a theory I've come up with that the second ''Galaxy'' game was sort of a midquel between the ending of the first one and the 121st star-ending from the 1st one, in which the universe was recreated by the Lumas' sacrifice, Luma was reborn while Mario was on his way to the new Star Festival, Bowser stole Lubba's Power Stars, Mario stopped him again, Luma was reunited with Rosalina, and everyone attended the festival as was shown during the 121st-star-ending from the first game.
* Assuming that, in-universe, Lubba and his starship did exist in the first game, even if from a developmental standpoint they hadn't yet been invented, and given there does seem to be some sort of intergalactic postage system in both games, why did Rosalina at no point think to try contacting Lubba and his crew to ask if they could borrow some of their Power Stars to power the observatory and stop Bowser that way...?
** Rosalina and Lubba have been out of touch for a while, and it's clear that Lubba's starship isn't in good shape when you meet him.
* How do giant Lumas work? They seem to appear only in the Supermassive Galaxy...How would Rosalina ever be able to take care of them? When they transform, do other giant galaxies form as a result? How many Star Bits would it take to sustain one of them?
* What's the true nature of the cosmic spirit that appears to aid you in certain galaxies? She looks like Rosalina, sounds like Rosalina, and has the same personality and manner of speech as Rosalina, but if it ''is'' Rosalina...how is she able to appear there in the first place? She spends the game being held hostage by Bowser - otherwise, she would've lended Mario and Lubba her aid a lot sooner - yet the cosmic spirit never seems to suggest that she's in any danger or mortal peril. She speaks about as calmly as ever, and neither Mario nor Luma ever seem to make note of the similarities.
** Nowhere is it stated that Rosalina is in danger, Bowser or otherwise. Besides, [[DidYouJustPunchOutCthulhu how likely]] would that even ''be?'' It seems that Rosalina is staying out of it because she knows you're in good hands (Lubba) and Bowser's threat isn't as destructive as last time. She probably has faith in Mario and Luigi to save the galaxies without needing much cosmic interference.
** What are you talking about? Have you seen the game's ending? Bowser's galaxy generator was trying to eat up Rosalina's observatory, and she was stuck inside it the whole time, and when she shows up during the ending, she says that she's been searching for Luma after she lost him...She would've shown up on Starship Mario, if only for that, if she could have. In addition, I don't think the protector of the cosmos would've let a threat as big as Bowser's be handled without her help, just because "it wasn't big ''enough''."
** Rosalina's pretty optimistic about the whole thing. All she says is that the power was drained. She probably stayed with the Observatory for the sake of her Lumas, not out of imprisonment, and trusted that Mario would succeed. So it seems more like a major inconvenience than mortal peril. To help, Rosalina projects some of her remaining power out in the form of a starry avatar, the Cosmic Spirit.
*** ^ I like that explanation...though, I still wonder why she never has any dialogue for Luma when Mario meets the spirit, considering she's always sending him letters filled with Star Bits and heartwarming, encouraging words.
