The player can make the possessed Sim talk with other Sims about a 'Normal Sim's problems', about flowers or about the ' Mother'. While possessed, the player has limited ability to control the Sim, and it will constantly override interactions with strange and dysfunctional interactions, such as wandering around or staring at objects. The Sim will then twist and contort a couple of times, creepy music will play, and their emotion will change into possessed.
Upon creating a batch of bizarre fruit juice, it will have a default description that says 'this fizz feels strange'. Drinking a bizarre fruit juice will also result in a sim becoming possessed. Vampires can also become possessed if they drink plasma from a Sim who has the infected trait. This special emotion can be achieved by collecting the bizarre fruit in StrangerVille and eating it, or by entering into a toxic cloud in the second level of the secret laboratory.
