Tripod Zombie:
1 Tripod
1 costume & mask

First  setup your tripod. Next take and dress your tripod. Use 2 of the tripod's legs for the legs of your dummy. The third leg is on the back side of your dummy and is only used to support the dummy from falling over. Pin/tie the costume to the top of the tripod (where it swivels). Now tilt the tripod's adjusting handle as straight up as you can get it. This will be used to support your mask. Lastly stuff the dummy and throw the mask on and you are all set.
