There are now official images of the LEGO Super Mario Super Mushroom Surprise (30385) polybag that is a free pre-order gift. The piece count is unknown at this time but you can get it with a pre-order of the Adventures with Mario Starter Course (71360) on Zavvi. This is currently the only place in the US to get this particular polybag. I’m not sure if other retailers will get it as well or not.
