How to Train Your Dragon 2!

While playing a game I learned that there was going to be a 'How to Train Your Dragon 2!' I looked around, and found this It sounds really cool! and I cannot wait for it to come out on DVD.

It is based 5 years later after the defeat of the Red Death. while the others are having Dragon Races, Stoick is telling Hiccup that he needs to become cheif! Hiccup refuses and flies away on Toothless. he finds a cave, full of unknown dragons! he also meets a dragon rider! He doesn't know it, but it is his mom!
(That was the basic summary that I could find) there will also be a How To Train Your Dragon 3 in 2016! I just can't wait!
