"YOU'RE BLUE NOW. THAT'S MY ATTACK! NYEH HEH HEH HEH HEH HEH!!!" - Papyrus, 201X

Similar to MEGALOVANIA, Bonetrousle has had quite a few covers on Notessimo. However, most of them aren't accurate to the OST. So, here's my cool take on Papyrus's theme, complete with the -- in my opinion -- inferior iteration that plays when not facing off against him, "Nyeh Heh Heh!"

Enjoy, and stay determined!

(P.S.: The blue soul in Undertale represents Integrity, one of the seven human traits.)
