That is awesome!!!!! I know you've put a lot of time into your body form but I agree with J-Man. You put someone in that costume, have them sit perfectly still until just the right moment.........You'll hear screams from a mile away
Last 2 years I did static props like a wax museum and did just that, wore a costume and only moved when they were right up on me. It works really well. I was going to wear my Frankenstein and rig on bar so I could pop it out and step out of the cage but I haven't decided which one I'm wearing this year. I have 12 of these oversized costumes and a handful of clowns.
That is a pretty intense costume and set up. However I do have to agree that you should figure out a way to animate him. That would definitely have the TOTs leaving their candy behind as they run screaming down the street. LOL!! Mmmm more candy for you. lol. ;-)
