Picnic basket

Picnic baskets are portable items that can carry food for Sims to eat at a remote location.

The Sims 3
The Fuzzy-Logic Picnic Basket is a portable group activity object in The Sims 3. It has a hunger rating of 4, and Sims can only eat from it if it's been opened, with a checkered blanket underneath.

Picnic baskets can be found in Sunset Valley's big central park, unless The Sims 3: Seasons is installed, where the park is instead replaced with festival grounds.

The Sims 4: Cottage Living
Picnic baskets return in The Sims 4: Cottage Living, functioning similarly to lunch bags from The Sims 4: Parenthood. Various types of food can be packed into a basket and stored in a Sim's inventory, including both purchased food and homemade food. It can then be placed on any picnic table, allowing Sims to gather around and eat from it.
