It can be grown in a pet's front or back garden by purchasing and planting the Glass Lantern Tree Seed at the Outdoor Store. This tree was added on March 14, 2011. After planting, it will take 72 hours for the tree to reach maturity. Afterward, the tree will begin producing fruit, one fruit at a time, randomly. A pet can have up to three total fruits on the tree at once, unless you have the Fruit Fairy, in which case you can have four fruits. Glass Lantern Fruit from this tree can be used to fish at the Pet Society Pond. These fruits will only catch common fish and decorative / junk items.
