Most will have items like bombs, swords, and wings but, sometimes you can get Dragoon and Hydra parts inside! (They are both legendary vechicles). When you find a piece,(which is floating and glows) pick it up like a normal item. When you all 3 pieces of Dragoon (or Hydra) you transform into it and you can use it just for that round. To unlock Dragoon in City Trial's Free Run, you have to complete tasks.
Part A: Jump 1,000 feet or higher in City Trial's High Jump.
Part B: In Start Mode, fly through the rings in the sky 5 times or more.
