The Forbidden Fruit is a type of plant that can be created in The Sims 3: University Life. It is one of the possible results of using the ZRX-9000 Science Research Station to perform the Gene Splicing Experiment on a seed. In addition, when PlantSims successfully "Try For Baby", the result is a Forbidden Fruit seed.
The Forbidden Fruit seed is a Special plant, and requires level 7 Gardening skill to plant. Once planted, it will require 4 days to fully bloom and be ready to be harvested. The player will be able to select "Tend Garden" or "Pick Forbidden Fruit". "Tend Garden" will produce an edible fruit, which will be placed in the Sim's inventory. "Pick Forbidden Fruit" has a 50/50 chance of producing an edible fruit or a PlantSim baby. The quality of the Forbidden Fruit plant plays a factor on the PlantSim baby's starter traits. A Forbidden Fruit plant only produces one fruit (or baby), and becomes barren after being harvested.
If an Alien picks a forbidden fruit, it will instead adopt a normal Alien baby. This is because the baby produced is a clone of the one picking the fruit up. Since Aliens cannot have occult life states, the baby cannot become a PlantSim.
An edible Forbidden Fruit can also be produced by using the Science Research Station to analyze a Forbidden Fruit seed and to clone the sample.
When a normal Sim who is a teen or older eats a Forbidden Fruit, he or she will receive a "Botanitis Minorous" moodlet. If the moodlet is not cured within 4 hours, the Sim who ate the fruit will become a PlantSim.
The Sims 4 Edit
On April 13, 2017, "The Plantsim Challenge" was released for The Sims 4. If a Sim collected all the Magic Beans and placed them in the magic stump, a tree would grow; a Sim could explore the tree to receive a Forbidden Fruit. If the Sim ate the Forbidden Fruit, they would become a Plantsim for 5 Sim days.
