Moray Towers has multiple floors to it, each at an angle. When the player runs towards a floor, they go on the downwards floor. The floors also act as soft platforms, allowing for multiple levels of fighting.
Right before the match starts, during the on-screen appearances, off-screen Inklings will fire ink at the stage, though this is solely for aesthetic purposes. When a player is in the lead, Judd and Li'l Judd will hold up victory flags from Splatoon and Splatoon 2, with appropriate coloring for the player/team (red if Player 1, blue if Player 2, etc.), and will also get launched into the air when a player gets KO'd. The stage also has a day and night version, chosen randomly when the battle starts.
