I've always been rather unimpressed with the official design for the Tails Doll. I've always thought his design was rather lackluster, and I especially have a pet peeve about his bear-shaped ears. In addition, the fact he's actually just another Eggman robot makes the official Tails Doll really underwhelming.
For my redesign idea, I went with a concept that the Tails Doll is more of a supernatural entity. The pendant is essentially his life force and will change colors according to his mood (oddly enough, red is actually "normal").
