At least, not until I found this.
I have found the greatest non-Transformers transforming robots coloring book of all time. This book isn't great because of the robots that look like your average Transformers, because they are rather generic (but still better than Go-Bots).
Now, the robot on the cover looks like some sort of bird. A hawk or eagle, perhaps. Even that seems like fairly standard fare compared to what is inside the book. You see, the best parts of this coloring book are the animal robots.
