For clarification, this is just a bunch of short extra gags included on the bluray release of the first season. All of them are variations of actual scenes that happened in the story, so they're best enjoyed right after the actual 12-part first season. They're understandably rather cheaply made, reusing existing shots multiple times and having only one unique piece of background art that I could notice, but that hardly matters much. They're good enough and exactly the kind of little extra I love when studios do. They're pretty damn hilarious so I actually rated them a point higher than the series (8 vs. 7) - sue me!
