what guesses did the londoners make about what mij was?

The Londoners made various wild and funny guesses about what Mij was. Some guessed that Mij was a baby seal, a squirrel, a walrus, a hippo, a beaver, a bear cub, a leopard, and even a brontosaur. These guesses reflected their unfamiliarity with Mij, who was actually an otter. The best remark about Mij came from a laborer who, after seeing Mij, growled and asked, "Here, Mister—what is that supposed to be?" indicating the unique and unusual nature of Mij.
