The covering of a humpback whale?

Answer 1

You would need a really big blanket to cover a whale. Here is a link to information about whales.
A whale is covered in a layer of 'blubber', a fat and flesh composite particular to whales, beneath an outer layer of thick, shaggy fur.

Answer 2

Humpback whales grow to be about 52 feet (16 m) long, weighing 30-50 tons (27-45 tonnes). The females are slightly larger than males, as with all baleen whales. The four-chambered heart of the average humpback whale weighs about 430 pounds (195 kg) - about as much as three average adult human beings. You can look at this website for more info on humpbacks. http://www.enchantedlearning.com/subjects/whales/species/Humpbackwhale.shtml
