Go to the flight deck on Chapter 11. When in the flight room where your ship "used" to be, look between the walkways. It is in the gap between Runway 1 and 2 by the shuttle in the Flight Hangar. You should see a tiny statue that has a golden appearance. Pick it up with kinesis and you will receive the Peng treasure (and its achievement or trophy). It can also be sold for 30,000 credits.
