A Red Box
Red boxes appear in the city trial mode of Kirby Air Ride. They often contain 2D squares, which give Kirby a copy ability to use for a limited time. Occasionally, a red box will contain a Dragoon or Hydra piece. It's impossible to tell which boxes contain copy abilities and which contain dragoon/hydra pieces, other than in the random event where all boxes contain the same items (in this event, the boxes that contain dragoon/hydra pieces don't spin). It can be determined in another less reliable method. The red boxes that have the Dragoon/Hydra parts won't vanish after a certain amount of time, like all the other boxes do. There will only be one red box with a part on the map at any given time (assuming that there are any boxes with parts), and after breaking a box, another will appear.
