I'm wondering what to be for halloween. Any advice?

I think, for halloween, it would be fun to be some kind of weird alien creature. Just make one up.
Make a bizarre foam head, and get a whole lot of plastic tubes and paint them so that they are alien tentacles, and connect them to bags of different-coloured goo so that you can squeeze out purple weird goo all over someone's front porch when you go trick or treating.
Well, one halloween, I'm definitely going to do that…

Why don't you do something original like display pictures of your mothers face. That will certainty scare everyone

How about a douche bag?

If you're thinking about minecraft you shouldn't even be allowed to halloween
