Yes, "punchy" is definitely the right word for it. I haven't seen animation this high-energy since...well, Gurren Lagann, and maybe the Lucky Star opening sequence.
The art style seems pretty different from most of the other recent anime, akin to the likes of Genndy Tartakovsky's work (Samurai Jack, Powerpuff Girls, Star Wars: Clone Wars) and a little bit of Jhonen Vasquez (Invader Zim) in that green dog. Is it a dog? I don't know.
For all the cuteness the content doesn't seem to be very G-rated, though. You may want to turn down the volume or don your headphones, because there's a lot of weird moaning in the trailer.
Watch it below. I'm definitely interested now. The show starts airing in Japan first week of October. Are you in?
