The underground
The way that you go underground in Pokemon Deluge is by taking on the role of amateur miner. This will allow you to explore the vast underground tunnels in the game.
You can find fossils in the Underground Tunnels, or underground. Just dig for them as you would spheres.

A Prism Sphere can be found in the Underground tunnels in Pokemon Platinum. It is simply dug up in the walls of the tunnels using the explorer kit obtained in Eterna City. The sphere is clear and shaped like a prism, and it is harder to find than the red, blue and green spheres. It is thought to be symbolic of the Pokemon Diamond version since it resembles the structure on Dialga's neck.
