I was messing with Chromia and watching some other reviews, when someone said that the front looks like a head it hit me! I was able to get Chromia as the chest, head, and right arm of her combined mode.Check out the video please! it won't let me upload the video but here is the link! YouTube - Possible Chromia Bike Sister COMBINATION!!!!!!!! YouTube - Possible Chromia Bike Sister COMBINATION!!!!!!!! please tell me if this looks correct and if it will work with Arcee if anyone has her! I believe that Arcee's left arm will be the combined arm, it will swing up and peg into a slot, her sidecar and two wheels will become the left leg, the third bike will have a piece that will also swing up and become the crotch and still be the left leg, the third one had said to be a repaint of Chromia, if so it will still work. I hope this info helps!
