Mario & Luigi: Bowser's Inside Story/Heartwarming
- The Koopa Troopa/Boo couple in Bowser Castle. Doesn't seem like much on the surface, but if you think about it, their love was strong enough to persist even after they were Brainwashed into being Fawful fans.
- The ending, where Bowser, while nursing his wounds after being beaten by the Mario Bros. gets a gift from his enemies: A cake with little figures of Mario, Luigi and Peach and Bowser's face right in the middle.
- Even more so in that he's always wanted Peach to make one for him ever since Super Mario 64 back in 1996.
- Starlow being the one to deliver it is also heartwarming, considering the Odd Friendship of sorts she and Bowser had developed throughout the game.
- In Bowser's "memory banks", after failing to repel the Bros., the synapse running the place takes the shape of a pixelated Peach for communication purposes. The synapse says the shape is based on "the host's most carefully preserved memory".
- Likewise, using copies of Mario and Luigi as his defense against intrusion into Memory Banks. Shows some respect that rather than following his ego, and having a fake Bowser to fight there, he has deep seated enough respect for the Bros' strength that his mind chose THEM as his defense.
- This theme (known as "Friend theme"). It's played whenever Bowser's friends are around (Broque Monsieur, Private Goomp, Sergeant Guy, Corporal Paraplonk). Even though he may be a villain, he does have friends who help and support him, which makes it all the more heartwarming.
- Bowser and his minions. Specifically the ones Bowser rescues from the cages. There was this odd sense of... almost family going on between them, with Bowser being the classic gruff-but-devoted Team Dad. After viewing Bowser as a Jerkass tyrant for years and years of games, it's both odd and touching to see that some of his minions genuinely like him and want to serve him.
