Pet Society releases buildable Roller Skate Car
To make the Roller Skate Car, you have to get the help of 20 friends. To do this, open up the Pet Workshop and click on the car. You can then either post a wall post asking your friends for help, or you can buy the item outright for 25 Playfish Cash. Once you've posted the wall post, 20 friends need to click on the link in order to help you unlock the prize.
The other items currently available in the Pet Workshop include the Hot Air Balloon, Playhouse, Party Invitation, and Magic Warrior statue.
