When young Bill's family was crossing the Pecos River on their venture to the West, he fell out into the river. An old wolf found him and took him in. The pack accepted him as their own and taught him the ways of the wild creatures.
One day, Bill was taking a nap, and a drifter named Chuck came riding up to find Bill sleeping with no clothes on. He asked Bill what he was doing and why he was sleeping with no clothes, and Bill tried to explain to Chuck that he was a coyote. Chuck didn't believe him and said that Bill was a Texan, just like him. Chuck lent Bill his extra clothes and taught him the Texan ways.
A while later, Chuck told Bill that most Texans were outlaws, and the worst of them were the Hell's Gulch Gang. He explained that even they would be okay if they'd become ranchers and herd the longhorns that wandered the land. Bill immediately headed to recruit the gang and make ranchers out of them, but he quickly ran into trouble when he was ambushed by a giant rattlesnake. He overcame the snake and squeezed all of its venom out, leaving it as skinny as a lasso and as mild as a goldfish.
Right after Bill made the giant rattlesnake his lasso, he was tackled by an animal that was part grizzly, part puma, part gorilla, and part tarantula. They wrestled until the monster became so dizzy that he gave up. No one had ever tangled with this two varmints and lived to tell of it, so when Bill went on to meet the Hell's Gulch Gang, they were shocked and made him the boss of their gang.
Bill told the gang that he was going to make respectable ranch hands of them and went on to snag a longhorn that was standing nearby with his new snake lasso. Then he exclaimed that cattle roping had just been invented. The gang went on to round up all the cattle in Texas, but Bill was still missing something. He needed a horse and went after the notorious white horse in the mountains named Lightening. He chased Lightening far and wide and finally earned his partnership.
After finding the perfect place for all of the cattle, Bill met Slewfoot Sue as she passed by on a catfish. He immediately fell in love and proposed. She agreed on two conditions. He had to buy her a dress with a bustle and let her ride Lightening to the ceremony. The first was simple, but the second ended with Sue being rocketed to the moon and back down to Earth until Bill lassoed a tornado to catch her. The couple rode the storm to California and landed on top of his parents wagon. Bill brought his family back to Texas, where his descendants are still herding cattle to this day.
