Quoting Kevin Wadowski
nice, how did you make that?
Ok, um, if you can, get a firefighter helmet. Find an exacto-knife and some scissors. Then cut off some of the top ridge and shave off the rest with the exacto-knife, chop a bit off the front and slice most of the back off of the helmet. Then get acrylic green paint and paint it,and let it dry. Does that help you? Ive tried with minifig caps, but they dont work.
