Update: Nintendo has unveiled the results of Splatoon 2's latest Splatfest, and the winner of this event is Team Flight. While invisibility was the slightly more popular choice, flight won more solo and team battles to take home the competition. You can see the score breakdown below.

All Splatfest t-shirts will automatically be returned the next time players start the game. All participants will also be rewarded with a number of Super Sea Snails depending on your Splatfest rank and team.
