* The ending credits of the first ''KatamariDamacy'', of all things. It's gotta be the ending song, [[http://www.youtube.com/watch?v=lX_53MNn23o Katamari of Love]]... it's so cheesy, but it's such a pure expression of hope...
** In the last flashback of the We ♥ Katamari game, the flashback is of The Prince's birth and how happy his father is. Either you'll cry at how beautiful and emotional the scene is, or you'll cry at the fact that now he doesn't even remember which of the cousins he is, and how he constantly makes fun of him.
* [[http://www.youtube.com/watch?v=hMmbv-aRovE The King of All Cosmos' backstory]]. The part where [[spoiler:the King's father fishes the second-place trophy out of the river]] showed that despite his strict attitude, he really cared about his son. When the young King runs to his father in tears, you can almost imagine him saying, "I'm sorry, father!" and his father replying, "I'm sorry too, son."
** The very first cutscene reveals just how hard the Emperor pushed his son, leading to uncomfortable implications about the King repeating the cycle with the Prince. Even after living through all of that firsthand and knowing how badly it screwed him up, he still treats his son like TheUnfavorite and acts like he doesn't even remember him at times...
* ''Katamari Forever'': after the King wakes up, the [=RoboKing=]'s anxiety kicks into overdrive: what's the point of having a ReplacementGoldfish once the original comes back? Then the King learns about him, and [[spoiler:is absolutely ''furious'', ordering you to dismantle him at once. [[CrueltyIsTheOnlyOption You have no choice]] but to roll him up as he lies there helplessly, piece by piece. The happy, cheery ending sequence feels [[MoodDissonance pretty darn dissonant]] for anyone who liked the poor [=RoboKing=].]]
* If the game over screens [[NightmareFuel don't scare you]], they'll probably make you outright depressed. Seriously, the king REALLY knows how to emotionally kick you while you're down.
-->''King'': We knew We should have asked your cousins instead of you. This is not your fault, but Our fault for believing in you.
