yes there are: Pocket Frogs, Dragon Story and Tiny Monsters
Many people like DragonVale. I honestly love DragonVale.
Yes there are a billion! Just go to google and type in DragonVale Cheats. and there you go!! :)
Yes with jailbreak
The DragonVale app itself allows you to do this. Look in the market; you can purchase decorations and buildings.
Dragon Story
Sorry, But No
DragonVale has not published any physical books. So far, all the books reference the game are in an e-format.
DragonVale is only available for Mac iTouch products such as the iPad, iPhone, and iPod Touch. You can find similar games, such as DragonCity, on Facebook.
It is available any time.
You delete DragonVale the same way you do any other app on your device. Hold your finger on the DragonVale icon. When it begins to shake, a red X will appear in the corner. Simply touch the red X.
Not sure, but I don't suggest jailbreaking and cheating on games.
It is impossible unless you were signed in under Google Play Games
