Perfect Mysteries:
Pond Punk
You might not even know what Pond Punk is.  If you look around, in Chicago, you will eventually find it.  But getting is a mystery within itself...
The sign looks normal enough, in the streets of Chicago.  But don't let if fool you- this is no ordinary building. 
The main purpose of Pond Punk is to have a second Falcon 2.  So once you find the second Falcon 2, you can leave, because there's nothing else to see, right?
Wrong.  In one of the stalls, there's a piece of the pieces of cheese!  I wonder if somebody crapped it out or something.  For more on the cheese, see my Cheese section under Mysteries.
