Ok, so basically I just found these HTTYD names trademarked by Dreamworks.
Before it was Dreamworks Dragons: Gift of The Night Fury it was:
Dreamworks Dragons: Secret of the Holiday Hatch
And before it was Dreamworks Dragons: Book of Dragons it was:
Dreamworks Dragons: Book of Dragon Secrets
Book of Dragon Secrets
To be honest these are some pretty cheesy names, that's probably why they changed it. I also found another one Dreamworks trademarked- Dreamworks Dragon Trainer, not sure what that was there for though.
Sorry for the lack of posts lately, but HTTYD Riders Of Berk, just aired and boy was it awesome!!!! The animation is not as good but it was great nonetheless!
SPOILERS!!! Quickly scroll down to miss this part!!
The episodes included were-
How to Start a Dragon Training Academy and Viking for Hire.
Sypnosis- How to Start a Dragon Training Academy:
The island of Berk, having trained many dragons they thought life would be peaceful, but dragons will be dragons and soon the dragons start stealing food and creating chaos around Berk, watch as the teenagers try to put a stop to the havoc and create peace on Berk once more.
Sypnosis- Viking for Hire:
All Gobber used to know was being a blacksmith and creating weapons to fight dragons, but because dragons have been trained he has no use for blacksmithing, so the teens try and help him find a new job.
Several people have LiveStreamed it so if you would like to watch it I suggest going to Crownflame's LiveStream of Riders of Berk by clicking here! After that click on the video titled either- 1: How to Start a Dragon Training Academy or 2: Viking for Hire.
Cartoon Network has put up a new Riders of Berk page, which you can see here!
Character Profiles- Kinda short for a profile, but cool nontheless.
Games- DTA- Legends- Basically, if you don't have the DRAGONS- Double DVD pack with the code, these are just the legend games from the Dragon Training Academy game.
Videos & Clips- Good if you are in the US, because it doesn't work for other countries- like here in Australia :(.
Good fun! They are likely to add more content soon.
