Swapfell Papyrus Headcanon
When Papyrus was a babybones, he had a hard time when he was teething and the habit never stopped. Till this day, Sans still has to stop him from chewing on random objects because Sans is tired of putting money into repairing Papyrus’s teeth. That’s why if you look in the silverware drawer they have flat spoons from Papyrus chewing on them until they become almost unusable for liquid meals.
