I had a werewolf dildo from Bad Dragon that I got specifically because Halloween was coming up.
I made the mistake of getting it in super-realistic colors, though, and wound up giving it away even though it was an awesome toy. The colors were just a bit too much.
The Leo's also really cute, and even though the texture would probably kill me I'd love to grab a Cyborg simply because robots are sexy as hell.
Though cyborgs don't really scream "Halloween" at me.
