Crystals on Club Penguin?

 

If you waddle to the Dock, Beach, Snow Forts or Forest, you might notice that there are crysals burried in the snow. Hmm...

Snow Forts:

Forest:

 Dock:

Beach:

When you click on them, nothing happens. I think it's related to the Marvel Super Hero Takeover, but in what way? What do crystals have to do with anything??
