Balloons appear in a variety of colors, tied to a weighted string that keeps them suspended in mid-air. In Battle Dojo, Balloons are decorated Battle Dojo's logo. Likewise, when found in Turf War, balloons are decorated with the Turf War logo.
Balloons act as targets when testing weapons and Splatoon's controls. In Battle Dojo, each popped balloon awards players one point until there is one minute left in the round and the amount of points awarded doubles. In the Single Player mode, if the player pops a balloon, he or she will recieve varying amounts of power eggs.
