* [[http://www.youtube.com/watch?v=VDBpQVhCMb8 The Mario Kart Love Song]]. Who knew playing a racing game could be so sweet?
* Sometimes, if you're playing as [[{{Adorkable}} Luigi]] and he falls off the track, he will say, "Thank you!" to the Lakitu who rescues him.
* In Double Dash!! When you finish the race, the two characters you chose celebrate together. While this leads to the obvious niceness with pairs like Mario and Luigi or Mario and Peach, it becomes really sweet to see [[DistressedDamsel Donkey Kong and Peach]] or [[EnemyMine Mario and Bowser]] so pleased with each other. Especially during the award ceremony.
* In the section right before the cave on Double Dash's Sherbet Land, there are two Shy Guys skating together. It's a small, but sweet sight to behold
