Unlike previous Sims games, the Cow Plant is a reward that you get from accomplishing aspirations. Your Sim will know the recipe from then on so if you consume a Bizarre Fruit after the story's conclusion, you'll still need to collect the ingredients and make another vaccine dose to cure yourself. The infamous bovine flora that comes in the shape of Cow Plants makes a return in The Sims 4.
If you wish to rid yourself of the possession, you'll need to work your way through the StrangerVille storyline to make and drink a vaccine. Still, it's a hilarious side effect that doesn't cause long-term damage. If a Sim gets possessed before a work shift or during a date for example, their progress for that event will be compromised. The downside is that you have no control over when the possession happens. I click on the seed and it had the option to plant but it is grayed out. In this way, the Bizarre Fruits can be used in the place of sleep and give your Sims a boost in other areas of their lives. Sims 4 I can’t get the life of me figure it how to drag and drop the seeds from my inventory into my planter box. They won't decay until the possession is over, which generally lasts about three hours.
However, when a Sim gets possessed, all six of their meters will top out. They will not be able to interact with any object, and any social interacts will be ignored for the purposes of the relationship meters. When this happens, while you'll retain direct control of your Sim, they will ignore all commands aside from Go Here and some basic but creepy interaction with other Sims.
