The costume starts with an idea. I spent quite awhile thinking what my 10-year old boy might love. Star wars trooper? Alien? Ninja? Well, I probably can make a not bad snow trooper costume, but admit it: there are hordes of troopers out there on the streets and they are plain boring. I was looking for something standing out of crowd, wild, ridiculous, having as much Halloween spirit as possible and I was totally failing to come up with something cool. And when you, parents, can't solve a problem there is only one way to proceed: ask your child.
It appeared that he already had the idea fully baked and polished in his head and the idea was CYBORG PUMPKIN! What can be more ridiculous and Halloweeny than a Cyborg Pumpkin? I don't know. I think that was an awesome idea, so we both proceeded with discussing the implementation details right away.
In this instructable I'll explain all the steps, successes and mistakes and I hope it will help you to come up with a great costume for the next Halloween. It doesn't have to be Mutant Cyborg Pumpkin™®©:, so start your own project from step 0: Come Up With a Cool Idea.
