Game of Thrones: The Complete First Season arrived on Blu-ray on Tuesday riddled with bonus features, including seven commentary tracks, a pop-up guide to the series for each episode, and a rather lengthy complete guide to the mythology of the series, not to mention a slew of other awesome goodies.

But tucked within the set are a few hidden features. Traditionally, hidden features are called easter eggs, but adding a twist that fits the show, HBO calls these little hidden gems "dragon eggs."There are six hidden goodies found within the set, and rumor suggests they consist of audition footage from the cast. Last night, while crafting our review , we attempted to track down all six hidden features, but came up a little short.We did, however, discover five of the hidden features when we put the disc into a BD-ROM and played each video file separately. The sixth dragon egg, allegedly an audition with Jason Momoa, eluded us.IGN user Linnmeister has tracked down all the Dragon Eggs. Here's the breakdown of where to find them:"While the video is playing, open the features menu and scroll to the bottom. When the dragon egg becomes available another scroll down arrow will pop up. Scroll down and select the egg."Disc 1: Sansa Stark (Sophie Turner), during the character bios in the feature menu. Viserys Targaryen (Harry Loyd), during the scene where they first meet Drogo.Disc 2: Syrio Forel (Miltos Yerolemou), when he and Arya first meet. Sandro Clegane ( Rory McCann ), during the joust when Petyr Baelish is telling Sansa how the Hound got his scars.Disc 4: Drogo(Jason Momoa), during the speech about invading Westeros.Disc 5: Arya (Maisie Williams), in the "Making of" featurette while Maisie is talking about the books being to adult to read.Thanks for the help, Linnmeister. The fans of Game of Thrones offer you many thanks and praise!Be sure to still follow HBO on their Twitter and Facebook pages for trailers and previews of Game of Thrones: Season Two.
