Sea Excavating/Seashell Buffs

[Kamikaze Mongoose]

Sea Excavating
I was collecting coral and seashells yesterday and it gave me an idea: sea excavating. It would be neat if you could use a metal detector to comb the ocean floor for baubles and other small treasures. Here are some things you could find:

• Coins
  
• Chests/Safes
  
• Jewelry
  
• Scrap/Debris
  
• Robot parts
  
• Ore
  
• Active landmines
  
• Gems
  
• Smooth stones
  
• Artifacts
  
• Sea glass
  
• Trilobite nests
  
• Petrified wood
  
• Fossils
  

Seashell Buffs
Seashell collecting is fun, but a large part of the hobby is collecting seashells that are unique or very high quality. Here are some things that could spice up seashell collecting on ocean maps: 

• Seashell quality levels
  
• Variations among size, coloration, and type
  
• Crafting uses
  

1. Sedimentary beach stone design for tiles/walls with holes, seashells, organic matter stuck in them.
