This one has some pretty uncommon parodies that I don't think we have tags for. There's Time Travel Tondekeman (https://anidb.net/anime/265), a manga by Atsuji Yamamoto called Sinbad (which I don't believe shares very much in common with the classic story), and Ariel (https://anidb.net/anime/2368), which is shockingly under-represented in general among doujinshi. Of those, I think Ariel should at least get a tag (and perhaps for the three characters as well), since it still has at least a semblance of popularity these days.
