go to ultimate contest, first buy everything from the sales guy. then keep talking to people and when it says do you want to give something to them, u say yes and and look for them again and keep doing that until u have no more items. then walk around and go to different places and do the missions . finally after finishing all your missions, go to the nindo and do the 50-man challenge. that should get u all of them if u do it right.
