The locked box can be found inside your zoo. Clicking on it will show you that a poor creature is trapped inside the box, which is locked with four locks. You’ll need the help of four different Zoo Paradise neighbors if you want to see what’s trapped inside – simply post a news item to your wall, and your friends will hopefully click on it, thus allowing you to open one of the locks.
Conversely, should you not think that you have enough neighbors to open the box within the three day time limit, you can purchase the keys outright for a whopping total of 599 Facebook Credits, or the US equivalent of $59.90! This isn’t the first time that CrowdStar has priced one of these events at $60, so it shouldn’t really be surprising by this point. Will anyone really pay that? It’s doubtful, but stranger things have happened.
