Six minutes, no arc, no stakes, and you will still watch it twice. This is Moyashimon's whole gimmick stripped down to its purest form: the microbes, the little round bugs Sawaki can see with his naked eye, finally rendered as actual 3D objects instead of hand-drawn blobs floating over a shot of fermenting mash. It was never sold on its own. You got it by buying the limited edition of manga volume 9, which means owning it is a flex about how deep you were in Ishikawa's agricultural school weirdness back in 2010. There is nothing heavy here, nothing contemplative in the prestige sense, just a light little bonus reel for people who already love A. oryzae more than most of the humans in the cast. Completionists know exactly why this one sits on the shelf.

Moyashimon gets a brief computer-animated treatment in this 2010 OVA, a single episode that runs about six minutes. Rather than airing on its own, the short was included as a bonus with the special edition release of the ninth manga volume. It is a comedy with supernatural elements, offered as a small extra for readers of the manga.
