When you feed mulch to an animal, at the bottom, there is a happiness meter. When you hover it tells you how many mulch the animal has capacity for and how many you have fed it so far. The enter button turns green as soon as you have fed the animal one mulch, but chances of winning improve the closer to the animal’s capacity (maximum happiness) you are.
If you do not win, you will also get the following popup reminding you to try to collect more mulch next time.
The animals on the top tier, the Perennials have a special bonus. They offer bonus zones, similar to the groves and animal totems, but instead of a mastery bonus, you will get a bonus of 5xp per animal harvested in the bonus zone. Read more about them here
There are five possible colors of mulch, red, green, yellow, blue and brown. Each animal will crave a specific color of mulch for a set period of time as shown in the picture above and then it will swap to a different random color. When the mulch color swaps, you will retain the happiness for as much as has been fed to date, but additional feedings must be done with the new color. As you can see below, the pig has switched from craving yellow mulch to craving blue mulch.
Mulch is obtained by harvesting crops. According to the guide in the official Zynga forums, every crop in Farmville has been randomly assigned a mulch color that it gives. When you find mulch in your crops, you will receive a popup indicating what color.
Some crops that give specific colors are listed below. This chart will be updated as we learn more information.
