First, the misunderstanding; later, the teamup.
Transformers Animated: Attack of the Dinobots! is a Transformers Animated storybook. Scheduled to be released in summer 2008, its author is Aaron Rosenberg. Rather than have someone illustrate the pictures, the pictures are screen caps from the episode, Blast from the Past, which this book is based on. A major difference between that episode and this book is that Prowl and Bulkhead don't rescue the Dinobots and put them on an island. Instead the Dinobots are presumably melted down by Isaac Sumdac.
