Do a few challenges around the island (target range, race, whatever) and get some trophies. Then find one of the two claw machines. There is on each of the two main islands but the easiest to get without exploring much is on the first main island where Aëmoon Port is. It is in an arcade not to far from the city center/bazaar type area. Once you find the claw machine, equip your trophy from your backpack and drop it in the receptacle (that has pictures of trophies), this will give you chances with the claw machine. From there, just line up your selection (first to the right and then forward), aiming for the targeting to highlight one of the balls. The claw will drop and if you are lucky... it'll grab a ball and you'll win something (and get the trophy).
