The gold piggy skin can be obtained by solving the puzzle in Piggy Chapter 1: House. This secret skin which was added to the game to celebrate the Bloxys will turn your character into a golden pig with wings and a golden sword.
To unlock the gold piggy skin you need to unlock a safe by solving a series of puzzles, this will involve using the Gold Key and turning four clock faces a certain way. Although it is not necessary to play in a team, you will find it a lot more difficult trying to complete the required tasks if you attempt it alone, as piggy will solely chase you.
To begin with, you need to grab the Golden Key which can be found on a bench in the basement. Make sure though before you leave the basement you touch the wall that is located left of the crawl space. Doing this will make the Basement clock face (III) appear. Now travel through the crawl space and touch the left wall that joins the ramp. When you do this, the Ramp clock face (IV) will appear. From here you need to run up the ramp and into the house. As soon as you enter the door of the house, you need to turn right and touch the wall by the bench to make the Downstairs clock face (II) appear. Once you have done that, run through the dining room area and upstairs to the next floor. When you reach the top of the stairs, turn left through the doorway and then turn left again and run down the hallway. Now touch the right wall, which is close to the nearest door and parallel to the bench. There is a possibility that you may have to hug this wall to make the Second Floor clock face (I) appear. Stay in this room as is the first clock face you must press to solve the puzzle.
Once you have found all four of the clock faces, they must be pressed in a certain sequence to solve the puzzle. You will notice that each clock hand has a specific color, and it is this that must correspond to the Roman numeral color. If you press a clock face out of order, all the clocks will reset, forcing you to start over. The order the clock faces need to be pressed is:
- The Second Floor clock face (I)
- The Downstairs clock face (II)
- The Basement clock face (III)
- The Ramp clock face (IV)
Once you have pressed the clock faces in the correct sequence, so they are all set, you need to head up to the top floor. To reach the safe you will need to use the floorboard. All you need to do now is open the safe and click on the Gold Piggy Bloxy statue to unlock the gold piggy skin.
