Ah - the neck is still molded to fit the original head. A minor annoyance but I think I can live with it. I don't mind the original head, but since Grimlock essentially has two "character" type modes, this new head is definitely more accurate. Just got Grinder on Monday and spent about 10 minutes with it before I packed it up with the other Dinos for the move. Can't wait to have all of these guys on display together!
