EDIT: You all suck XD It's a cowplant from The Sims 2. It's a carnivorous plant. If you don't feed it enough, it sticks out its cake-tongue lure (complete with candle) to attract some prey. In the shape of Sims. Once the cowplant has devoured a Sim, the plant's owner can then milk it, to get some elixir of life from the dead Sim.
See, I have a Sim Edward, and he... well, he really doesn't get along with people. At all. It can go completely wrong if he gets teased even once, leading to him making enemies and wanting them dead ('See "Sim's" ghost' want). He also gets wants to 'drink' that Sim, referring to the cowplant's elixir.
(Ed's also a nutcase and wishes bad things on people he likes, like for them to be zombies, or vampires, or be abducted by aliens. Gotta love them knowledge Sims).
