Instead of going to Walmart and buying some creatures for your lawn why not build your own?
“Our gargoyles are hollow rubber skins, supported by an internal skeleton of PVC pipe. Note that the garg is sitting on a “rock” that is also molded into the skin. We’ll put the fogger inside that area. We tucked a fogger under the garg, in the space between the skeleton parts. Ductwork carries to fog up, around, and out the mouth. Note that the fogger is firing towards the back of the garg. This makes the ductwork easier.”
