Help Hiccup teach Vikings and Dragons how to live together and build up the village of Berk. As your Dragons grow, so does your Village. Berk starts off as a small island, but it does not stay small for long. Toothless is automatically unlocked for you at the very beginning of the game. He is Hiccup's Dragon. His abilities include collecting Fish, Wood, Runes, Iron, Collection items and Dragon Eggs through Explorations. He is the only Dragon which can go on Searches in specific locations. 
You can defend your Berk against Alvin's attacks and even test the strength of your dragons while having them brawl against each other. 
You can currently have 30 Dragons on Berk. This includes Toothless, but none of the Journey Dragons which are attached to their corresponding huts.
