Bowery
Across from the museum and south is a building with a maze on it. This is also the same building where you can change characters. There are two generators and a switch on the roof and a ball in the cage. Use the generators to move the ball. Since each generator can move in two directions, you can move the ball in all four directions. The switch will open two gates inside. You just need to get the ball to the other side of the maze so you can retrieve the trophy.
From the jammer on the roof of the museum, turn north and directly ahead and above the train tracks is a statue.
