Why Did Nintendo Send Me A Rock In The Mail?

I’ve received a lot of peculiar things from Nintendo in the past: A DSi cake, a call from Mario, a box of candies, but this is the first that made me work to find out what it was.

Inside today’s package was a large white rock with the words Fossil Fighters cut into its surface. Digging deeper into the shredded paper that filled the box I also found a chisel, a brush and a large piece of brown paper.

To work then.
