Shrek
Meet Shrek! This incredible sheep avoided shearing for almost 6 years. It is quite like its name, awesome! He really didn't like getting a haircut, he grew such dense hair on himself to look like a cloud.

This is what it looked like
This sheep from New Zealand managed to avoid being shaved its hair for 6 years by hiding in the cave. That's too smart of an animal. He was then found in 2004 and his owners were shocked and mesmerized by the appearance.

20 men suits
The modern farmer stated that Shrek's wool produced more than 20 men's suits. It had to be sheared as the wool will keep growing more and more and it won't be able to see or do anything.

Evolution
The domesticated sheep evolved on how humans groomed them but the Bighorns from the west shed wool every year. Animals evolved a lot with humans.

Shrek needed help
Shrek had to be sheared as it needed more help than the humans needed its wool. It had to deal with vision impairment and mobility issues and also heat stress.
