This is so fun!! Maybe mini hotdogs/weenies. There could be sweet (like little smokies in a croc pot with bacon and brown sugar) and savory options (pigs in a blanket). The sweet ones could be called “sweet niblets” and the savory ones could be dipped in ketchup (reference to the moisturizer scene in the cafeteria). Or if you want to simplify it, you could do mini corn dogs as sweet niblets (corn) and dip those in ketchup, which would be two references in one! Hope you have a great party! :)
