Random Pixels: Submarine Map Necklace Bag

I rolled the idea dice and came up with a submarine, a map, a necklace and some sort of bag. The map and necklace together suggest pirate treasure which works well with the idea of bags full of gold. Add in the submarine and you get sunken pirate treasure.

Of course nothing but a big old treasure chest underwater would be kind of boring so I threw in a mermaid.
