Hello everyone. I got my Jazz today and discovered some tips to help people properly transform him. They don't fix his chest issues but they make it more secure and I didn't notice for a few hours. First off is how far the chest moves. On mine it tends to get hung up here: But with some gentle manipulation it is supposed to go this far: Next is the more inconspicuous tip. He has a pair of slots on his back: And they don't get used unless you know to use them. Or at least I didn't use them for a few hours. With these two tips you can make Jazz be completely solid. His chest does not flop around at all. He's super solid. He still isn't perfect but he's not too bad.
