Instructions
Reach at least level five to receive your first visits from sour pinatas. After level five, new varieties of sours come to your garden at three- to five-level intervals.
Select the sour that you want to domesticate to collect information about it, including its bad habit and the requirement to tame it.
Allow the pinata to carry out its bad habit. They are not receptive to your attempts to tame them until this has occurred.
Carry out the sour pinata's requirement to be tamed. This ranges from feeding it a particular food item to increasing the distribution of water in your garden. It often involves the sour doing the opposite of its bad habit to learn the error of its ways.
