These are just a set of 6 couple minute skits (I believe the longest is like 5 min), and in my opinion, they aren't that funny, but you can watch them all in like length of a normal episode, so there's really not a point in skipping them if you liked the show. Also, I swear one of the skits was a repeat from an earlier episode. Anyways the rest of this review will be really short sense its basically a 1 episode review.
Story: 4, Not really any story, but for pure comedy I split the score 1/5 Story and 3/5 Comedy for a total 4/10. Pretty similar to my score for the main story, but 1 less point in comedy.
Art: 7, same score, the art maintains its quality and consistency.
Sound: 8, lost one point from original anime because there was basically no music.
Character: 6, same score
Enjoyment: 6, lost one point, I didn't find it quite as funny as other episodes.
Overall: 6, this is okay, just not as good as the original anime.
