You don't really have to watch the 1st season or 2nd season to understand the 2nd season specials. You can jump in straight. But you do need to watch the specials to understand the 2nd season. The second season specials are truly a masterpiece. The first season specials were really good too. But i would rewatch the second ones more. Story : I wasn't really expecting a story this good honestly. I just wanted to watch the specials quickly to get back to the show but the specials story was better than 1st and 2nd season's story combined. Art : I wasn't really into snake girlsbut now i totally am. The art was that good. 100x times better than the 1st season episodes.

Sound : There is one soundtrack that's really really good. Part of my desire to rewatch is cuz of the music.

The only thing i would have preferred is these 3 special episodes made into a movie instead cuz that really would have been one good movie competing with the top ones.
