The Dark Horse Presents site on MySpace hosts a second Beanworld short story in the issue number 32, March 2010. Go over here for the 2-page story teasing the next phase in the Beanish/Dreamishness relationship.
(note if you have trouble with the MySpace site, as I often do, you can read the story over here)
Still over a year before we get to the next book, SOMETHING MORE, but remember there are regular teasers for it showing up on Larry Marder’s Blog.
