It was very cute. I could totally see this in a children's book. It was so simplistic, it could probably be made in any language (english, japanese, french, etc.) It's nice to have something that isn't violent or random slap stick comedy every once in a while.
The style almost reminds me of My Neighbors the Yamadas (by Miyazaki). It has a certain charm to it :)
See that little kids? if you don't stop watching T.V. you'll never get facial hair. xD
