The platypus's fur is waterproof because, as a semi-aquatic mammal, it still needs its fur to keep it warm. If both layers of its fur were constantly saturated, the platypus's body temperature would drop too low.
Further, the platypus must make hundreds of dives daily to hunt enough food to eat. If its fur became waterlogged, it would not be able to swim as easily and agilely, because it would be weighed down by the extra mass of the water. It would therefore not be able to hunt as effectively.
The dense fur of a platypus is waterproof. Its very density enhances the platypus's ability to swim discreetly through the water, seeking food whilst barely noticeable.

It is called "Damien" and is in the first season, and to be accurate he is turned into a DUCK BILLED platypuss.
I believe the beaver possibly has the most dense fur.
