1. Get a Pinata with non-expensive Resident requirements (as in you do not have to spennd a lot of money to get it).
2. Whack the Pinata with your shovel (and gaurd the candy).
3. There will be one special candy, the pinata's life candy. Sell it, it's worth 4 more coins than the pinatady Trick (you can also sell the other candy for more money).
