This is a wonderful coin cheat that my friends always use and it is not a hack.
1. Go to camppiggy.com and download Firefox for free
2. Open up Firefox and go to club penguin
3. Go and play cart surfer and get at least 100 coins
4. Go into the town and look at your money
5. You should have 5,000 more coins.
After you do all of the steps you can repeat steps 2-5 as much as you want.
Also this is not a hack, trust me, non of my friends ever got banned from this.
