Finishing out the trilogy of books released by Viz Media today is the Ponyo Picture Book. These are published for every Ghibli film as a companion piece to the official art books, and they're enjoyable reads. Definitely something more for the kiddies, as they usually retell the story with lots of bright and colorful pictures.
This book is a distant third in my shopping list today, but I'm sure many of you are eager to pick up a copy. You can buy from Amazon here.
