I'm not sure specifically as I don't know which 'the contest short story' you are referring to. It could be about a competition, perhaps a writing contest where the story itself is either the entry or about the experiences within the contest.
It's not based on a true story. The story of Walrus is likely the creation of the author's imagination, perhaps inspired by various fictional concepts and themes.
Well, for a YA short story contest, common requirements include a word count range, like 3,000 to 8,000 words. Also, the story might need to fit within a given genre or topic. And often, there are rules about originality and submission format.
First, have a clear understanding of the contest theme. Then, do extensive research if needed. Polish your writing, check for grammar errors, and make the story emotionally resonant with readers.
The back story of 'the walrus and the carpenter' is often about a devious plot. The walrus and the carpenter trick the oysters into following them. They seem friendly at first but have ulterior motives, like wanting to eat the oysters.
I'm not entirely sure specifically what the 'obey the walrus' real story is. It could be a very niche or local story, or perhaps a reference within a particular community or sub - culture that I'm not familiar with.
