These specials were included on the BDs when they were released in 2021.
The creators handpicked 16 scenes (one from each episode) from the main show and decided to make comedy skits out of those, even the glorious scenes got the parody treatment.
As a big fan myself, I couldn't skip this entry, I love SnK and I am always prepared for anything.
If you you watched the former seasons' chibi anime released, you will definitely know what to expect, it's in the same art style with little to no changes than WIT.
Go ahead and have a good laugh, detach yourself for 10 minutes of the depressing world of the main anime.
