Well, I need a little help with two costumes. The Shaggy costume takes precedence as I'm using it at a Halloween party, and for trick or treating (Yes, I'm nearly twenty and I still trick or treat. I like free candy thankyewverymuch.

)
For the Shaggy Costume, I'm wondering what kind of props I should use, and how to expand on them a little better. I'm also not sure quite what color of hair dye I'll need (It needs to not be long lasting). My prop list so far consists of
-A little Scooby Doo Plushie
-A box of "Scooby Snacks" ((Need to find something to put in said box that looks like dog snacks but actually tastes good, or maybe just use it for trick or treating)).
-Possibly a small mystery machine thing.
M. Bison I'm putting together for Gencon next year, and...I have NO IDEA where to start. That I'm going to need a lot of help with, but isn't as much a priority as the Shaggy one, since it's almost another entire year for Gencon, but the Halloween party is in less than a month.
