This season is good so far, but I love anything with zombies in it
The rock wall I made from 1/4" polystyrene styrofoam. I had two large sheets so I used one sheet to make two 'base' pieces and then tore pieces off to make rocks and siliconed them to the base piece to form a rock wall. Then I painted the walls with 4 coats of unsanded tile grout, 3 coats of gray acrylic paint, and 4 coats of Krylon sealer.
