How is appearance different when the ducks first see him from way he describe in passage?

When the ducks first see him, they describe him as "a very small creature with no fur or feathers, brown skin and a smooth tail." However, when he describes himself in the passage, he says that he has "smooth, sleek fur, a tail that was bushy like a squirrel's, and black eyes that sparkled like diamonds." This shows that the ducks' initial impression of him was very different from the way he actually appears.
