Well it's actually a close tie between monokuro boo and mamegoma. In case 你 didn't know monokuro boo pigs are black and white pigs. Their slogan is "Simple is best" they are one of the most 流行的 san-x characters. Mamegoma is also very popular. They are little 密封 blobs. But all in all I would have to say mamegoma is my favourite. They won my 心 when I first saw their game. link http://www.youtube.com/watch?v=ioMIwAYx3XM&feature=related
