Antique Coin Production[]
Once the Mud Wallow has been built, it will start working once there are 4 adult (not baby, nor prized) pigs in your farm. After 
18 Mud Droplets, the Mud Wallow can be clicked to get 
10 XP and 3 to 6 
Chunk of Clay:
| Chance | Reward |
|---|---|
| 70% | 3 Chunk of Clay |
| 15% | 4 Chunk of Clay |
| 10% | 5 Chunk of Clay |
| 5% | 6 Chunk of Clay |
The player yields one Antique Coin as long as there are at least 4 adult pigs (prized pigs are not taken into account). If there are fewer than 4 then the Mud Wallow will not work. The Antique Coin can be a Bronze, Silver or Gold one. The chances of getting a Gold coin change depending on how many adult pigs you have. You have to have at least 8 adult pigs for the maximum chance to get a Gold Coin.
| Chance | Reward |
|---|---|
| 65% |  Bronze Antique Coin |
| 25% |  Silver Antique Coin |
| 10% |  Golden Antique Coin |
If the Antique Coin Collection consisting of 
6 Bronze Antique Coins, 
4 Silver Antique Coins and 
2 Golden Antique Coins is completed, the player wins the exclusive Spotted Hog, which in fact is a Black Pink Spotted Ossabaw Pig.

Once you hit level 10, you get access to the Mud Wallow.
Building phase 1 of the Mud Wallow requires some materials. You get 9 of them up front.
Second phase of building the Mud Wallow requires help of neighbors. 2 are already provided.
Once finished, the Mud Wallow will be able to generate Antique Coins.
Once you harvest the Mud Wallow, you get an Antique Coin provided you have enough adult pigs on your farm. Otherwise you only have a chance of getting them.
And once you filled the Mud Wallow's Antique Coin Collection you will be awarded with the Black Pink Spotted Ossabaw Pig. This so far (march 2013) is the only animal capable of making
