Social Bunny

The Social Bunny is an NPC in The Sims 2 that visits Sims when their social need is too low. Like the Therapist; only the lonely Sim can see it.

Raising the social need
Just having the Social Bunny around raises the social need, but the lonely Sim can interact with him anyway to raise it, ranging from friendly kisses to outright fighting. The Social Bunny leaves when the bar is back up to the halfway point.

Multiple Bunnies
If multiple Sims are in social failure, the other bunnies will be seen when a lonely Sim is active. However, they will be invisible, and cannot be interacted with.

The bunnies may interact with each other, though. Social Bunnies come in three colors which are blue, yellow, and pink. Generally, Social Bunnies of a different color will be friendly with each other, with blue and pink ones going romantic. However, much different sparks fly when two bunnies of the same color meet, as they'll actually fight with each other.

Friend bug
There has also been a bug where the Social Bunny can actually become a friend. (eg. he comes to parties, goes on vacation, visit, and possibly all the other things that normal friends can do).

The Social Bunny vs The Tragic Clown
When The Sims series started, the social bunny was not the first NPC to show up to depressed Sim's houses to cheer them up, it was done by the Tragic Clown in the first game. The tragic clown came whenever a Sim's mood was half-way low only if there was a painting of him hanging around somewhere. However, the Social Bunny came when the Social need was empty only. One key difference between the two is their success in trying to make depressed Sims feel better: The Tragic Clown always made matters worse while the Social Bunny managed to bring the low social up to 50% high.
