The pre-order bonus for Sonic Boom Fire & Ice for the 3DS has been revealed by the Nintendo EShop. It is a DVD with at least 3 episodes of the Sonic Boom show on it. The blurb at the bottom tells you it will have episodes that contain Shadow & Metal Sonic for sure. Since the Boom show has not been released on disk or as a set yet (as of summer 2016) it would be an ok way to be able to collect some episodes. Once released, an episode list will be added to the entry.
