Head over to the Mystery Box section of the Happy Pets store (it’s found under “Goods”), and you’ll see a new, pet-based option, in addition to the two item-based mystery boxes.
The Premium Pet Box can be purchased for 16 Facebook Credits, and according to Games.com, will allow you to receive a new pet (so long as you have room in your home for one) that would normally cost 18+ Facebook Credits from the store.
While rare and otherwise retired pets are available to find here, remember that more basic “premium” animals like plain turtles, pigs, and bunnies cost 18 or more Facebook Credits, so you may very well end up with one of those, rather than something extravagant.
Is it worth the cost? We’ll leave that decision to you – if you do decide to take a chance, though, let us know what pet you receive in the comments! We’d love to know if you feel it’s worth the purchase!
