Gym badge #8
The eighth and final gym, you guessed it, features a complex puzzle that you must surpass to challenge the Gym Leader. The puzzle is a series of button and gear puzzles that, as you go, rise in complexity. In the first area, head onto the walkway and onto the green button. Head off of that section and onto the section you walked onto to get to the green button. Step on the next green button tomove the paths again. Now you have access to the next room. In the next room, head onto the small section and repeatedly step on the blue switch until your section connects with the one next to it. Head back onto the main floor, up the flight of stairs and the newly placed bridge. Then step on the next blue switch which will connect you to the next green switch, which in turn will bring you to the other stairway and bridge set. In the next and final room, head onto the section with the red switch. After the rotations, head off the section, and onto the other and to the next switch. Head up to the next level and onto the section with the green switch. Rotate the sections until the all join together. Head over and onto the blue switch. Now, head down the newly accessed stairs and across the bridge to the first level. Now, step on the red switch, and then head back up to the second level. And, voilá, you now have access to Vaulkner.
