If you walk in the National Museum of Australia you’ll see something very strange. Among the artifacts and Aboriginal paints is a roll of some 90 pounds of wool. Why you ask? There’s definitely a story behind it.

In the fall of 2015, a group of hikers saw a sheep wandering around by himself north of Canberra in southeast Australia. But something stood out about this sheep.

He is a merino sheep, which are selectively bred to not shed their coats each year. This means they must rely on humans to shear them. This sheep was roughly five or six years old and must have been on his own for years because he had a massive coat of wool on him.

Concerned that he wouldn’t survive the summer, the hikers contacted a rescue group who sent out a message to request help from an expert shearer. Ian Elkins, a four-time national shearing champion, answered the call.

The sheep, who had been named Chris, had to be anesthetized while they sheared him. Because he had so much wool, it took nearly an hour to shear him. Typically the average fleece weighs 11 pounds when sheared and only takes a few minutes.

As soon as Chris woke up, not only had his physical appearance changed, but his personality was immediately apparent. Before the shearing, he could barely stand and didn’t want any human contact. Afterwards, he was craving attention and wanted to be petted.

Luckily, Chris was in relatively good health for what he’d been through and is now at home on a nearby farm. Check out the video below to learn more about Chris and be sure to share it with your family and friends.
