I should have done a DIY type post for it but I was in a hurry. Basically the sides and back are made of insulation board. You can buy it at Lowe’s or Home Depot. A 4x8 foot sheet of it is under $20 from what I remember. The skull and rocks are made from a type of rubbery styrofoam that was being thrown away where I work. It’s the type of styrofoam that is used to protect electronics when they are shipped, not the dry brittle type. I pretty much just drew the skull out and carved it into shape. Same with the rocks.
After that, I used non toxic acrylic paint and my airbrush to paint them. Sealed them with a water based acrylic sealer and it was done. All together I might have $40 in the whole thing.
