yep. And I've had people come up to my table at the MLP fairs, and guiltily tell me they think they customized a part-white blue belle... My response: "Oh well, I wouldn't beat yourself up over it, you didn't know!"
After all, the customizer is the one out money, not us, lol. I mean, sure, it's a shame when a rare pony gets customized, but if the person left it to rot away in their attic and never customized it, we would never have gotten those piggies in the community... So if you think about it, the near-loss of 1 saved others.
