#...IF THIS DOESN'T SECURE YOUR FRIENDSHIP... WORRY NOT HUMAN! I HAVE AN INTRICATELY COMPLEX BACKUP PLAN!!! NYEH HEH HEH!!!

I keep thinking the bones Papyrus has been gifting Undyne are actually quite rare, as a show of his friendship. Perhaps he even gave Frisk an extra rare one when they visited Undyne for the first time. It seemed to work for Papyrus so why wouldn't it work for the human? Besides he has a backup plan anyways, reverse psychology and an excellent escape route.
