Sickness
A good gardener keeps his piñatas happy and healthy, but that's not always easy! When piñatas lose a fight, get whacked with the shovel, eat sour candy, eat poisonous plants, or are not given enough room to roam, they may become sick. A sick piñata lies on the ground looking and sounding miserable.
You may call Doc Patchingo to heal a sick piñata for a small fee. If left untreated, the witch doctor Dastardos will make his way to the sick piñata and break it.
Also, if you have a Chewnicorn in your garden, you may direct it to a sick piñata to heal it. Note that after a Chewnicorn has healed a piñata, you will have to wait some time before it can heal again.
Additionaly, the accessory Halo of Hardness will automatically heal a sick piñata that has it on.
Broken piñatas
When a piñata is broken, it will float to the edge of your garden and reform as a wild piñata, losing its name and any accessories it may have been wearing. The candy in the piñata will be left in your garden for other piñata to eat.
