Hidden Objects Pirate Treasure

A pirate captain wants help finding treasure, and each cave-island scene hides a list of objects tucked into rocks, water, and piles of loot. It's a short, simple hidden-object game without much beyond that core loop: find the list, move to the next scene, repeat with a new picture. If you want a light pirate theme layered over the format rather than added mechanics, it fits the bill.
