Undertale references in the Simpsons

Undertale references in the simpsons is an idea created by AskGus. As the franchise is popular ( and with simpsons knocking off obscure things ) it'd be hilarious to see a sans reference is someone mentioned a skeleton pun or mentioned about a bad time. It'd be funny to see papyrus to see that someone's feeling blue hense of papyrus's *special* attack. Undyne would be in something where somebody is unnecessarily stopping in a big chase because of a phone call.
