Mysterious Black Clouds at Dojo Courtyard!

If you head to the Dojo Courtyard, you'll notice something different... the clouds have mysteriously spread and turned black!

What could this mean...? The only thing that I come up with is Card-Jitsu Snow or Card-Jitsu Shadow!

I'll be investigating, but stay on the look up penguins!

What do you think? Tell me!
