Draw some round shapes and rainbow colors and you've got a hit, as we know from the PPG, probably CN's most successful show in merchandising plus the movie. The American version of Смеша́рики (Smeshariki), Gogoriki, has been airing for the past few months. I've only seen it a couple of times. It's ok, just ok (intended for ages 3-8), but I still find it the most appealing cartoon in the 4kidsTV lineup (which is not so hot). It's for kids but it's not overly kiddie (a good thing), which is mentioned in the video. I don't imagine this would be such a big hit in the US, especially with 4kids's track record and the already well known Happy Tree Friends, which parodies cutesy rainbow animal types by abusing all the characters.
