Darn, I hate to be a spoilsport, but that is actually faux lizard skin. Snakes have single ventral scales, not a series of rectangular plates like that "skin" has.

Lizards are just snakes that haven't gotten around to losing their legs yet (at least most of them), so don't feel too bad.

And since the ventral scales are really called "scutes", you can pleat it to those and be biologically correct.
