You can thank my G3 obsession on Starswirl and Sparkleworks -- I saw them at TRU and HAD to have them. The rest, you know, is history... Some of my favorite ponies are Kimono, Snowflake, Dazzle Surprise, Cherry Blossom, Moondancer, and Star Catcher. They are, I think, all the perennial favorites, but I don't mind being common in my tastes.
