>^..^< Sprinkle is my favorite! I love cats and anything retro-looking, so it was love at first sight when I saw the swanky kitty for the first time. I like Poochie and the other retro-looking images from TCP's early days. I'm always disappointed when there are no Sprinkle sets unveiled during the new releases events
As for the other characters, I quite like the Penguins for Winter and Christmas sets only, and I like a couple of the PJ and Bunny sets. I don't like Big Bear, the Sheep or OuOu Kids at all... sorry. I'd like sheep sets though if they were drawn more like the Sprinkle, PJ and the Penguins characters.
I hope I haven't offended anyone with my opinions!
