Halloween trees are a type of garden tree that produces the homegrown fruit, Homegrown Halloween Lollys. They can be grown in a pet's front or back garden by purchasing the limited time Halloween Tree Seed at the Garden Shop.
This tree was introduced to the Facebook version of Pet Society on October 19, 2009 as part of a Halloween theme.
After planting, it will take 72 hours for the the Halloween tree to reach maturity. Afterward, the tree will begin producing fruit, one lolly at a time, randomly. A pet can have up to three total lollys on the tree at once.
Homegrown Halloween Lollys from this tree can be used to fish at the Pet Society Pond. These fruits will catch only common fish and fishing junk.
