Yeah I've know this guy for about 2 years and been to his house a few times and I know it's been boarded up, condemned for something, I have others say it is the spiky thing on the iguana but if you look closely, or even invert the colors you can see the difference in color and shadow.
Here I circled where the figure(circled in red) seperated from the spiky thing, and you can see the figure is separate from it.
