Dragon Planet: How to Raise Your Dragon is game that lets you explore the ins and outs of dragon care, ranging from egg handling to medical treatment, feeding and more. There are 20 planets, 20 dragon eggs and 20 different dragons in total.
Each level has tasks that need to be performed. For example, you'll need to dig up the egg, clean it, perform an ultrasound, break the egg, and then care for the dragon. Each dragon you successfully care for will unlock the next level.
Follow the on screen instructions to care for your egg and raise your dragon. Who knows, you might find Trogdor the Burninator somewhere along the way. Probably not. Almost definitely not. But maybe?
