A complete online multiplayer round in the demo version of Splatoon 3 for the Nintendo Switch taking part in the first Splatfest event featuring the threeway rivalry of Rock v. Paper v. Scissors. Team Rock (including MacDaddyNook and MinionMancer) take on Team Scissors on the Museum d'Alfonsino map.

On August 27, 2022, the first Splatfest in Splatoon 3 took place in a special prerelease demo version of the game. Unlike Splatfests in previous games, those in Splatoon 3 feature a battle of three teams instead of the usual 2 with the theme for this one being Rock v. Paper v. Scissors. In addition, a new threeteam battle mode was also introduced exclusively for the new Splatfest format.
