Balloons are a decorative object in The Sims: House Party, The Sims 2, The Sims 3 and The Sims 4.

The Sims 2
The Poppin' Party Balloon Centerpiece can be purchased from buy mode in the "Party" sub-section. After a certain period of time, the balloons will pop and leave a mess behind that must be cleaned up. It can be placed on a surface or on the ground.
