There may have been a 'Cat in the Hat' but think we all enjoy a 'きい in the Hat' so much more.
Did a post many, many pages back for a short film きい appeared in last November on the Hikari website, she announced on her blog a DVD of all the movies is coming out on September 17th, I can't view the movies but here's the link to the site again if perhaps you're lucky enough to be able to watch them: http://www.hikaritv.net/sp/24jyoyu/#sect01
