Legend of the Dragon - 2005 Chow Chow 1-9 was released on: USA: 12 October 2006
To get Super Dragon Chow you have to have a Dragon Amulet. It gives 5 points, and you can get it from the quests Deap Freeze, Bombing Run, Gorgoks Return, The Long walk, Flight Training, and the Elemental War. I suggest you do the Long Walk (Found in Sunbreeze Cove) OR Goroks Return (in WillowShire) This Information was found at dfwiki.com so if theres a problem, dont complain to me.
you buy it
5 or 6days/weeks
I dont think it's actually possible for your baby dragon to 'age' aside for it's grown form in titan battles and other such things, dragon chow just gives it points to spend on it's stats.
