Laganaphyllis simnovorii

The Laganaphyllis Simnovorii (commonly known as the Cowplant) is a bizarre bovine vegetation that is large enough to swallow next-door neighbors whole. Friends will be hard-pressed to resist the tantalizing vine-cake of the carnivorous Laganaphyllis Simnovorii.

Career Reward
The Cowplant is a well known career reward in Natural Science in The Sims 2. It is most known for eating innocent Sims for lunch. The Cowplant sticks a slice of cake out on its tongue, luring the Sim close to the plant; then eats the Sim. After a cowplant has his lunch (a Sim), the owner can milk the plant, and the "milk' is actually a life-extending drink similar to the Elixir of Life. The Sim dies immediately, but unusually, the grim reaper doesn't appear, just a grave next to the cowplant. A memory pops up in the memory box about this action. If not fed it will attempt to eat a Sim every 12 hours. It can be fed by clicking on it and selecting "Feed". When this is done, the Sim will take out a Leg 'O' Lamb (this costs §35) and throw it to the plant, sometimes playing with it or teasing it first. This action is not automatic. Household Sims will ignore the plant unless it kills someone or the player directs them to interact with it.

Some Sims have a want to 'drink' a certain Sim that they are unhappy with. This refers to that Sim drinking the life essence of the offending Sim using the cow plant. This is a quick and easy way to kill off unwanted Sims. Controllable Sims can be ordered to "Grab Cake", and they will die if not stopped.

Be warned that this object may eat your friends.

Note: Toddler(s) and children cannot interact with the Cowplant aside from the children being able to feed & milk it. They cannot take the vine-cake that the Cowplant offers after not being fed for the 12 hour duration.

The Sims 3
The cowplant appears buyable but as tame and statue-like. In fact, as the cowplant doesn't move at all, it probably is a statue and not actually living. It can also be seen on the gardening channel eating a woman.
