I CHOOSE YOU LITTEN! Icon

420 choose it! Litten is the fire type starter of Pokemon Sun and Moon. Rumors say it might evolve into a ground type which means it's cutness might die out. They'll be sure to set your foes ablaze from the hair of their chin the kitten'der blocks bellow!

I can see US!Papyrus choosing this little fella, mainly because it's personality and has a fitting color pallet. Also could light his cigarette and irritate US!Sans by leaving flaming hairballs everywhere. 

Most likely am choosing Litten but...I also really like Poppilo. And knowing what happened in X&Y I might get Litten end game if I choose Poppilo.

Litten belongs to Nintendo and GameFreak
Icon by me.
