Instructions
Go to the Nexus Jawbox, the place where players donated bricks for use in building the Nexus Tower, in the Nimble Station world. Carefully jump around the leaning tree, using the arrow keys on your keyboard.
Turn immediately right after passing the tree, and stop on the Crux launch pad. This will allow you to transport to the previously unreachable area behind the Nexus Gate.
Maneuver your character so that it can walk through the set of trees that immediately appear after you land on the launch pad. Walk behind the Nexus Gate to find a new area that was previously blocked, with goodies such as a smashable box (used for extra points or awards.)
