Social Bunny is one of the pre-made social bunnies in The Sims 2 who resides in Pleasantview and custom neighbourhoods. Like all social bunnies from The Sims 2, he can't be made playable without cheats. When Social Bunny appears in custom neighbourhoods, his interests will be different from the ones he has in Pleasantview, seen below. Like all social bunnies, he has 30 personality points, instead of the usual 25.
Social Bunny appears to have an invisible face genetic, because if the player cheats to make a Sim pregnant with him, the baby will appear to use some of the facial features from the 2nd face template once they become a toddler. They may also have some facial features from the parent that gave birth to them. However it is unknown if he has true facial genetics since these are also the facial genetics a Sim will inherit from a Sim with no facial genetics. The Grim Reaper also has this oddity.
