Join Buddy Bison and how two new friends as they explore the majestic Yellowstone National Park. Breath-taking photographs of Yellowstone serve as the backdrop for the wacky adventures of a curious pair of twins, Elena and Christopher, who are spending the summer with their aunt Rosa, a park ranger.

Instead of waiting patiently when their aunt gets an emergency call, Christopher wanders off. That's when Buddy Bison, the adorable plush toy clipped to Elena's backpack comes to life and to her aid. The unlikely pair head south on a wild adventure through Yellowstone to search for her brother. As soon as Buddy leads Elena safely to her twin, her new oversized pal disappears. What happened to Buddy Bison? Did Elena imagine him or did he really come to life? Thus charming tale is sprinkled with helpful titbits about the park, weird-but-true facts about the animals, and more fun facts kids adore. A comprehensive afterword offers a short history of the park and ways kids can get involved in parks preservation.
