Item description:

Inspector
Finish a game of Pair-Matching in less than 3 minutes

Walk up to area left of Portal entrance
(Cursor already on it - Click X)

Once you're in the HOS....
You need to press DOWN on the D-Pad to access the matching game

The way the matching works is that you're matching up paired objects
instead of identical pictures so for example:
tire tracks goes with tires, footprints go with shoes, etc.
