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.
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.
The White whale (Balaenopara musculus) was one of the largest marine mammals. They are usually described as white, streamlined, about 30-40 meters long, weighing about 150-300 tons. Beluga whales are social animals that often form huge schools of whales that live in the depths of the ocean. They feed on small algae and communicate and court mates by swimming and whale dancing. Beluga whales were an important member of the marine ecosystem and an important subject of scientific research.
Yes, there are some very strange and rare medical conditions that could potentially make it seem like a man is 'turning into' a walrus - like some extreme forms of hypertrichosis which can cause excessive hair growth all over the body, along with certain deformities that might, in a very strange way, give an appearance somewhat reminiscent of a walrus. But it's not a literal transformation in the magical sense.
Yes, there might be. In some regions where walrus hunting was once common, there could be true stories related to their tusks and items made from their parts, like a walrus - skin suit. However, with modern conservation efforts, such stories are more about the past.
I'm not sure if there is a truly factual story about a man turning into a walrus. It could be a very strange and rare medical condition that might seem like such a transformation, or it could be a fictional or misinterpreted story.
