This might not have been exactly what people were thinking about when you said you were going to be "an amazing spider, man." Semantics, right? Who wouldn't want to be a giant arachnid? You get four extra arms, you can make a web and just chill while your food comes to you, and best of all you can scare the bajeebers out of people who wander near you. All that goodness is just one simple costume away.
