Although continuity plays a big part in Usagi Yojimbo's world, with recurring characters, arcs that span 4 or more issues, and situations that take years to pay off, there are also a lot of stand-alone stories, in which the long-eared ronin stumbles into a situation and becomes inevitably wrapped into.
The good thing about those kind of stories is that they allow Stan to write pretty much any genre he chooses without having to worry about future repercussions. So he can choose to tell a funny story, or a horror tale, or to tug at the reader's heartstrings (read "A Mother's Love" and cry yourself a river) - all of them a testament to his multi writing skills.
Another good thing about UY is its educational value. According to the introductory notes to the story, "Grasscutter pt. I" was used as a textbook in Japanese history classes at the University of Portland. Others teach you about making swords, soy sauce, transporting ice and so on.
So, this is a short self-contained story in which Usagi is involved in a dispute between seaweed farmers and helps them settle their problem. It was done during the 16-issue Mirage run and, therefore, it's in colour.
