Pumpkin

Jack-o'-lanterns are introduced in The Sims: Makin' Magic as buyable decorations. In The Sims 3: Seasons and The Sims 4: Spooky Stuff, pumpkins can be manually carved into jack-o'-lanterns, serving as a light source and/or decorative object typically during the season of fall/autumn.

The Sims: Makin' Magic
A jack-o'-lantern is a floor or table decoration in The Sims: Makin' Magic which also functions as a dim light at nighttime. It can be placed (and moved around) but not deleted unless the "move_objects on" cheat is used. On residential lots, it will eventually rot and have to be thrown away.

The Sims 3: Seasons
In The Sims 3, pumpkins are harvested through the Gardening skill, and will be placed into the inventory of the Sim who harvested the crop. Once harvested, Sims can interact with the pumpkin by carving a unique design on it, after which Sims can place a light inside, or smash it. They can also be bought at the Grocery Store. Sims can make pumpkin pie if they have at least five cooking skill points.

The Sims 4: Spooky Stuff
In The Sims 4: Spooky Stuff, pumpkins return as one of the new gameplay features of the pack. Sims can interact with the pumpkins just like in The Sims 3, although they can no longer be simply grown and harvested. They are made through a Pumpkin Carving Station.

Pumpkins will spoil after four days. Sims can preserve pumpkins so that they will last indefinitely. If a Sim smashes a pumpkin while the candle is still lit, they may catch on fire.

Pumpkins come in four colors: Orange, Pale Orange, Green, and White. The following pumpkins can be carved (for a listing of require skills see Pumpkin Carving Station):
 * Cockeyed
 * Classic
 * Cat
 * Ghost
 * Smiling
 * Owl
 * Scared
 * Puking
 * Wicked
