Souvenir
You can help The Sims Wiki by adding it.
The Sims
Souvenirs are added to the game with the Vacation expansion pack. In general, souvenirs in Vacation are won in carnival games, but they can also be discovered while fishing, or uncovered while using a metal detector. These items are placed in the Sim's inventory and will stay there until the vacationing family comes home. At that time, if there is space on a souvenir shelf or in a souvenir cabinet, they will be placed there. Otherwise, they will be put on the nearest available surfaces. These souvenirs can be sold in Buy mode, and may increase in value over time.
If a player clicks on a souvenir and selects the "Remember" interaction, the Sim will pick up the item, gather a crowd, and apparently tell the story of their vacation.
Carnival Games
Some Vacation Island lots have carnival games, which cost between §2 and §20 to play. Sims earn tickets from the games, and the tickets can be taken to a vendor ("Barney the Carnie") and exchanged for a variety of souvenirs. Body skill appears to affect how well Sims do at the games, and therefore how many tickets they win. Also, the more expensive games tend to yield more tickets. Some players have observed that Sims seem to get better at the games the more they play them, but this is unconfirmed.
