Early this summer we posted an exclusive sneak preview of NimbleBit's upcoming frog management title Pocket Frogs, which is something of a follow-up to their popular Dizzypad. The developer has recently posted a video showing the game in action and provided us with additional screenshots.

Pocket Frogs is a game of raising, breeding, and trading frogs. Each of your frogs will have three specific genetic traits that they inherit from their parent frogs, which according to NimbleBit will result in "many thousand possible emergent species." There are going to be multiple customizable habitats to raise your frogs in, and players will be responsible for keeping the frogs healthy, happy, and well fed by taking them out to explore the�Pocket Frog pond.

Aside from breeding frogs, players will be able to get new frogs by ordering them in-game as well as trading frogs with friends via Plus+. There are also plans to have various challenges to breed certain frogs which rotate on a weekly and monthly basis and the frog store will rotate on a daily with new frogs to buy with in-game currency. NimbleBit is still hashing out plans on exactly how they're going to monetize�Pocket Frogs, but have assured me that players will be able to access absolutely everything in game for free and whatever in-app purchases they finally decide on will be intended for serious frog breeders and otherwise entirely optional.

Pocket Frogs will be a free download, available for the iPhone, iPod touch, and iPad, and will take advantage of the iPhone 4's high-resolution Retina display. The game is slated for a September 15th launch, and those who download the title in its first week will receive an exclusive frog, the 'Black Floris Tribus'.
