Bonetrousle is the theme for the Great Papyrus, an eccentric skeleton who is one of the most popular characters in the game Undertale (not that in-game Papyrus is aware of just how popular he is in real life). These original lyrics set the stage for Papyrus's characterization at the beginning of the game. Though he works hard to accomplish his goal of capturing a human, he does so largely for selfish reasons -- to join the Royal Guard and become famous -- while naively not really thinking of what consequences capturing a human would have for the human and for the monster community in the Underground. But how would he act when an actual human appears? You'd have to play the game to find out!
You observe the cool, confident, well-dressed skeleton standing before you.
"Wowie!" you think. "It must be that popular head of the royal guard! How I long to befriend such a great and important person."
Note: Not yet a member of the Royal Guard.
The Great Papyrus has just one goal; that is to capture a human for the Underground's king.
The problem is because of their souls being so powerful, catching one's a difficult thing.
I have persisted long for this moment with my puzzles and gates recalibrated, intact.
And I have cooked a bowl of spaghetti that I'll feed the human as a way to distract.
For once I win, then I, Papyrus, will have fame and many more friends than can be said.
They will be celebrating my greatness with paintings and songs and a hedgebush of my head.
Oh yes, I will have countless admirers, but do they sincerely like me, or is it all just pretends?
And could I feel at ease with myself when the human has to leave if we become friends?
