Crystal Skull

About
Crystal Skull was a sacred treasure hidden in the deeps. However, it was only a myth... or was it?

Crystal Skull, of course, the name explains all. It's a skull, but it's made of crystal. Archaeologists said that it was covered in the deeps, but citizens and folks think it's a myth, so was it a myth or a hidden treasure? We don't really know.

Movie
The Crystal Skull became famous and popular due to Indiana Jones : The Kingdom of the Crystal Skull, which is the first Indiana Jones movie ever... ever.
