My son got me started collecting them when we saw them at Walmart...then he showed me the videos and I WANT THE BEE KITTY!! I don't think they ever made one, but the one on the show is adorable!!
I did luck out and get all the gem kitties, including the two Claire's exclusives. That was pure dumb luck, though. The other sets I was never able to complete and I'm so disappointed with the Halloween releases. They sold out of the minis almost instantly and they don't have any plans to restock. The larger ones they have restocked a couple times, and it was the hope they would with the minis, since that set had some freaking adorable ones...witch, frankenstein, spider, bat...a bunch more. I'm not spending a ton of money, though. Claire's was bad enough at $20 a pop (although the last ones I managed to get on their recent sale, so about $13 each instead of $20).
I did splurge and get the large alien...too cute!!
