I almost think its from the sets that supposed to have went to Wal Mart cause I NEVER saw them have any of these figs at the Wally Worlds here in Denver. I've seen Snow Serpents, BATS, Barbeque, Bazooka, armored CC, Tripwire, and Wraith but not clear ones. I've heard reports of a Blowtorch around but haven't seen him which I'd love to find cause I could use one.
Ohio reported the ninja vipers in a place called Marcs as well, and Ollies on the east coast as well. So check those places as well.
