Not only is this a great Halloween costume, but you can also use it to intimidate your DM at your next D&D night. And a great tutorial by one Chris Mouser shows how deceptively easy it is to make. The petal-like headpiece is made out of Fosshape (theater nerd foam), with a chinstrap to keep that sucker on your head.
Then the gooey paste applied over it comes from a mix of latex house paint, food coloring, and flour. Please do not confuse this with the cookie batter recipe we've also given you.
