Short clips within each episode, these are decent. However, it looks like there are only 2 episodes @ 3.5 minutes and not 4 episodes. Using several key word variations to try and track any other specials down in both English and Japanese yielded multiple 1 minute clips, or the 2x 3.5 minute episodes that contains these within them. This should hopefully clear some confusion and save some search time.
The goal of these specials, like season 1's, is to be funny. This time they hit that mark a bit better I'd say. The expression of Shinoa in the back of episode 2 was amusing. Totalling 7 minutes, there isn't much else to say past that they are decent.
I would suggest watching these 2 short episodes for some decent amusement value (again, 2x 3.5 minute episodes is all there is).
