Stunt Kite Party

You just need to play any game (win or lose) with every Characters,skins and kites at least once. I suggest you keep track of them because there's a lot and most of them need to be unlocked.

Speaking of how to unlock them , they are all tied to the achievements in the game
- Complete the Story mode first
- Play and win every Cups (can be done with 2 controllers)
- Play Custom Tournament and go grab the remaining achievement (can be done with 2 controllers, except Full House)
- Once you play and complete your last match with the remaining skins/kite or characters, the achievement will pop at the end of the game.

Hope it helps !
