Toons 4: Cold Shoulder, the next part of the series that completes their journey in Looneyville, and will lead to the next journey. I'm also releasing all four parts in one book called Living in Looneyville. If you haven't gotten any of the series yet, purchasing the bundled collection is convenient and cheaper.
I've decided not to continue releasing the series as short stories, so the next book in the series will be about the same length as Looneyville, and collect their adventures in the black-and-white world of the Monochrome Zone. It will be called Color Blind. Or Fifty Shades of Gray. I haven't decided yet.
