* [[BigBrotherInstinct Mario]] leaping into the vortex to [[ThePowerOfFamily rescue Luigi]]. It's more heartwarming when you see that Luigi is the first person Mario tries to save, not Peach, Luigi. Brotherly love at it's greatest!

* A minor example, but at one point in chapter 2, Bowser calls Bowser Jr, asking him if he did his chores, such as his homework and taking out the trash, just like what any [[GoodParents good parent]] would do.

* Almost everyone's reactions to the Rabbids in general. You would someone expect the mushroom kingdom citizens to be afraid of the Rabbids because of their antics, right? This isn't exactly the case. Mario, Luigi, and Peach were somewhat confused by them at first, but they slowly warmed up to them. Even at the ending scene, a crowd of Toads and Rabbids wacthed a new statue of Rabbid Peach get unveiled. It goes to show how the Mushroom Kingdom opened up to these insane creatures because they've mostly [[SeenItAll Seen it all]].

* [[BigBrotherInstinct Mario]] leaping into the vortex to rescue Luigi.

* At the end of world 2, ''Peach'' of all people pulls a BigDamnHeroes moment, and poses with Mario as a BattleCouple.

** Any time Beep-0 tries to stick up for your Rabbid allies at the beginning of the game, really. His genuine concern over Spawny is also rather sweet, with him telling Mario he has to 'save' the Rabbid.

* [[BigBrotherInstinct Mario]] leaping in through the vortex to rescue Luigi.

* In one trailer, while everyone else is donning the appropriate reaction to Rabbid Kong, Rabbid Luigi just smiles and offers him a banana.

** Based on the game's ending; if you really think about, Mario, Luigi, Peach, Yoshi, and all the Toads may be the first amount of people to ever fully accept and befriend the Rabbids despite their chaotic antics.
* Bowser Jr's genuine gratitude to Mario and stark change in demeanor after the final boss shows that he loves his father so much that the fact that his own evil plan failed seems like a minor inconvenience to him as long as his dad is safe. The ginger way he treats Spawny is also quite adorable.
* In a meta example, the game’s title and some promotional artwork had been leaked weeks prior to the game’s initial reveal at E3 2017. The developers had been keeping as much as they could under wraps due to the [[BrokenBase naturally divisive]] status of the Rabbids, to avoid any ill will before they could show the game off. The leaked artwork was met with confusion and ridicule online, which, according to interviews with the development staff, made them question if they hadn’t made a huge mistake in the years developing the game. Come E3, and the public’s first chance to see the game in action. Its reveal trailer was met with a rousing cheer and applause. [[TearsOfJoy One of the developers, Davide Soliani, could be seen on camera crying,]] as he is a huge fan of Shigeru Miyamoto, and it was reported he camped out in the rain for hours outside Miyamoto’s hotel just for the ''chance'' to meet him. Then 15 years later he gets to work on a game starring Mario, Miyamoto’s creation. Not only that, he hears his hero compliment him on stage in front of the world, and praise him by name, on his hard work on this game. His smile and tears from being acknowledged by the man he greatly admires was truly a beautiful moment of E3.
