A chilly breeze caused the tent to flutter just when Spatoon finished setting it up. He wiped a brow from his forehead before admiring his handiwork. The tent he set up had been with him ever since he debuted as Splatoon, the metal-manipulator superhero. That's not the reason why he brought it with him though.
He was aware that the team had to stay on the lookout for who knows how many hours in the night, and it would be quite uncomfortable waiting by the port without something to shield them from the frigid air coming from the sea. That's why he brought the tent. It wasn't a place for relaxation, however, and he made that perfectly clear.
