am i the only person thats noticed different skins on certain building blocks?

[WarpedReality]

when i play against some kingdom players they have snakes on the kingdom building pieces instead of wings. i talked to someone that had them and they had no idea why. i'm just curious if anyone has seen this or knows how to get them?

oh and any low level guys that want some help learning the game feel free to hit me up on xbl.
