This tree was introduced to the Facebook versions of Pet Society on April 28, 2009.
After planting, it will take 72 hours for the papaya tree to reach maturity. Afterward, the tree will begin producing fruit, one papaya at a time, randomly. A pet can have up to three total fruits on the tree at once.
Homegrown papayas from this tree can be used to fish at the Pet Society Pond. So far, it appears that these fruits will only catch common fish and fishing junk.
