For those who kept complaining it's 3000 coins, just click on it and you should a pop up asking if you want to purchase it for 150 coins and an image of a win/lose box. If you do not see that, check this 3 criteria.
1.Database.dat is replaced with the database_wigdye.dat (It will be highlighted in gray if replaced)
2.You have cleared browser cache to ensure database.dat will appear in Fiddler
3.You have a brain and you understand simple English.
Now, if your answer is a NO to any of the 3 criteria, I'm afraid the cheat will not work for you :(
Steps:
1.Download Pink Throne Database
2.Open fiddler and replace database.dat and shopMystery.dat. The rule editor are as required
Regex:(?insx)^.*/shopMystery.*\.dat$
REGEX:(?insx).*database\.dat$
3.Reload Pet Society. If replaced correctly, the 2 lines will be highlighted.
4.Wear a wig first because you cannot dye a bald head.
5.Go to mysteryshop and you will see all the WIG dyes. Even the Petling biscuits can be used to dye your wig.
6.Go to mysteryshop/glow in the dark and you will see a pink throne. Click on it and you will see a message to buy it at only 150coins.
7.Sell them at 999coins each. Viola, easy money.
