I used Styrofoam (Packing from Flatscreen TV). The front of the mountain is comprised of 60 pounds of plaster, spray paint and Acrylic Paint used for the accents of the rock face.

The main entrance door was created from Card Board, scrap board, and Legos. It was then painted and weathered to the appearance of weathered metal.

The legend of a Cobra Mountain has always bothered the Joe team. Little did they know, it was buried deep within the Rocky Mountains. It took over six years using heavy machinery and B.A.T.S working around the clock to complete this massive hideaway. Over 2000 troops are housed here along with armour and a lab where Cobra's technology team work to bring more weapons to the battle front. Cobraaaaa!!!
