Celebrations were the second type of kart customisation added to Smash Karts.
When winning a game or getting a Smash Streak during a game, your selected celebration will be activated. Traditionally, celebrations came out of the 4 exhaust pipes at the back of the kart, but recent celebrations use different mechanics (e.g. Electric Overload).
Celebrations are available for Coins, in the Spinners and in the Season Track.
