I have only seen the Werewolf/Dragon with the one torso, but there is a rumor that the two torso pack is out.
Nice finds. I love the Puma Boy and Ghost Girl. The create-a-monster kits is what got us hooked. I got all of my stuff when it had a brief appearance on Amazon.com and TRU.com last week. Keep checking those site. They come back in stock frequently. Keep checking.
