Ok Last spot idea: Papyrus! Song is Bonetrousle. Papyrus looks awful. If papyrus dies, sans comes out! I got the idea from Brawlfan1 on Youtube. Papyrus would have one less health than he's supposed to, for sans's one hp Papyrus's victory animation would be he is laughing then sans starts playing trombone which makes papyrus mad. he audibly screams which is at the end of his victory theme.
@darksonicz had the song
