After the social bunnies that come with the game, Maxis has now published an easter bunny doll as a download. It's not really a bunny though, it's a mix of a rabbit and a bear, as a result of modern science:

"This adorably fluffy abomination of modern science updates the classic Teddy Bear with lovingly hand-stitched snippets of rabbit DNA sewn right into the fabric of the doll. Perfect for tea-parties, playing house, or playing God."

To have your Sims play with this little fluffy create, download it from the official site.
