Little Luke was born on a llama farm in the mountains of Colorado. His ears are long and curved, like bananas. His tail is short, woolly, and soft. On the day of his first trip with the pack of llamas, Luke gets distracted by a rattlesnake.

When he looks up, everyone is gone; they've left him behind. Luke wanders the mountain searching for his pack, meeting an array of creatures during his journey. He eventually finds a herd of unfriendly sheep. When there's an avalanche, Luke smartly helps the sheep get to safety. Once they are rescued, Luke discovers he's earned himself a new job.
