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.
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.
The so - called 'Man Turned into a Walrus' story has elements of truth. There was a person who, through a series of extreme body modifications, took on characteristics that made him resemble a walrus. This story is not only about the physical change but also about society's reaction to such extreme self - transformation. It challenges our ideas of what is acceptable in terms of body image and personal identity, and makes us wonder about the limits of self - expression and the human need to be different.
You'd need to show the scene realistically but also handle it sensitively. Maybe focus on the build-up and the consequences rather than the act itself.
Well, it's hard to say for sure. It could be inspired by real life, or it could be completely fictional. You'd have to look at the details and the context to determine if there's any truth to it.
