We like high-def Easter eggs around here and they can be from TV shows
to the Serenity HD DVD -- we don't care. This one comes in the form a 90 second featurette called "Fruity Oaty Good Time" and to navigate to this extra-extra, highlight "Extra" on the main menu of the disc and then press LEFT twice. This will trigger the Serenity logo that will take you to the said "Easter Egg." By the way, this Easter Egg can be found on the standard DVD the same way. We don't know what exactly is featured in the 90 sec video but we're sure it will be worth your time...we hope so at least.
