Makes me think of a funny story, My mom, sister, and aunt went on a cruise down in Mexico. My mom bought a really nice blue dress that was light weight, because of the extreme heat. Well, to make a long story short, it rained, and the dye from the dress dyed her blue from the neck to her ankles. This is not the recommended way to make yourself blue.
If you do decide to paint yourself blue remember this:
NO GLOMPING ALLOWED!! My wife had a very fun time trying to get some of the make-up off of our Silver the Hedgehog mascot costume. Please don't hug a large white furry thing if you are covered in make-up! One look at Mojo-Jojo had her quaking with fear.
NO TOUCHIE!
