Now this is a zeppelin with more than a little power to it. If you want to zip around the skies in inflatable style and technology, this marvel will be happy to oblige. As a replacement for theF4 - S.T Prototype Rocket, you can earn the means for this replacer as a rare drop or for a relatively light purchase in the market. Then you can zip around in your rocket powered dirigible at your leisure.
