It's a 5 minute 26 episode series, so you will be able to finish this in about an hour or two. Anyways, these "Nyanbo" are cats, well more like space cats or something of that nature & somehow they are on Earth. The anime? Stop motion? Well, this show features several different cat characters, with two being a brother & sister & a few other Nyanbos. The littlest Nyanbo is always hyper & full of energy throughout each episode & of course it also introduces two other groups of Nyanbo midway through this show. The Nyanbo are basically living in this attic of someone's house& they're also trying to look for UFO parts in each episode. I found this show to be enjoyable & of course the real life added into Nyanbo sure made it different from other anime.
