These are bonuses from the video renditions of the 4koma available on niconico. Since they're variations (And not official since I pasted them by panels), I've decided to just parent them to respective posts instead of pooling them along with others.
(Of course, I'll just be choosing those with noticeable differences to avoid redundancy.)
