Pretty creepy if you ask me. The animations are fine, but once they take on the puppet-like form, they look like something from a horror movie. In any case, I suppose marketing has shown otherwise. In Japanese, the product name is "gu-ru-to", and that is the name given to these characters from left to right "gu", "ru" and "to". 明治 グルト
