Deep Cut and the mechanic are seeking valuables on the Spirhalite Islands in Splatoon Raiders. The expedition is presented as a treasure hunt, with the group exploring the island region in search of valuable finds.
The trip follows Deep Cut’s discovery of a map in a basement. Shiver, Frye, Big Man, and the mechanic then travel toward the islands, where their plans are disrupted when their helicopter crashes. Exploration and survival become central parts of the adventure.
“Treasure” is the broader story term, while “valuables” accurately describes what the group is hunting. The goal is not to collect power eggs, find sea scrolls, or recover fictional tickets. Those options draw on familiar Splatoon objects or treasure imagery, but they are not the stated objective of the expedition.
