Pet rock

Pet rocks are pet objects in The Sims 3: Pets, which Sims can pick up and cuddle. While the possible interactions with them are limited compared to minor pets, they do not need to be fed, and can remain in a Sim's inventory indefinitely without breaking loose.
They cannot bite Sims either, but have a small chance of falling down on and hurting a Sim's foot.

==Notes==
*The Titanic Toy Machine has a possible craftable toy called Baby Bricks-A-Lot, but it's treated as a regular toy rather than a pet rock.
*Buydebug (if Pets is installed) has an object called "Bits of Rock", which appears to be either an Essence of Pure Love Rock or Gonk Rock broken into 3 pieces.
