You're walking back home after some weirdo at the gym asked you what kind of girl you liked. He was very weird... On your way home, you noticed that the air was getting quite cold... almost too cold for a summer. Then the air got much warmer suddenly when you heard something blow up a nearby home. Looking up, you see it... Skeletron Prime... firing it's cannon on basically any man-made object it can find. Everyone is panicking, as would generally be the case of a flying skull shooting bombs from a floating cannon. The other three hands aren't really doing much, occasionally just shooting a laser at a person, or chainsawing the random "hero" trying to stop it from this destructive rampage. You hear music playing from its skull, and it's really loud. it doesn't seem to notice you, what do you do?
