Career rewards

Every career has its own reward object which a sim can unlock after reaching around level 5 of their chosen career. Some of these objects are very useful and can be used as careers themselves, such as the chocolate making machine. All the items that increase a skill do so at a faster rate than any purchaseable item, and allow a sim with a higher skill to "Give Lessons" to another sim, accelerating the learning process even more. All career reward items are free but are limited to one item per sim per career. The career reward can be transferred from house to house through the inventory which was introduced in Nightlife.

Players who do not have either FreeTime (with up-to-date patches) or Apartment Life should note that the medicine will not work properly, though it can still be sold. And it sucks. A third-party fix is available.

Laganaphyllis Simnovorii
Natural Science

"This bizarre bovine vegetation is large enough to swallow your next-door neighbor whole. In fact, it WILL eat your neighbors. Your friends will be hard-pressed to resist the tantalizing vine-cake of the carnivorous Laganaphyllis Simnovorii. After it has consumed some prey, milk it for sweet, rejuvenating nectar of life. A swig of this liquid refreshment will add precious days to a Sim's life and wash away any regret they may have over their visitor's fate."

The Cowplant is a well known career reward 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 expanding drink. 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 selecting and clicking feed, the Sim will take out a Leg 'O' Lamb (this costs §30) and throws it to the plant, sometimes it will play with it/tease it first. This feed action is not automatic and must be ordered by the player.

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. Controlled sims can be ordered to "Grab Cake" if not stopped they will die. Otherwise household sims will ignore the plant unless it kills someone.

Be warned that this object may eat your friends.

The Sims 3 Career Rewards
I could find no evidence of them but careers now work very differently to the sims 2, you don't just get skill points and move up the ladder, you have to have the right skills, get on with your colleagues and boss and in some instances do certain other things (for example my sim was in journalism so she also needed to go to the theatre and right reviews on shows and interview sims and publish them).
