When Guppy the Puppy's family takes a trip to the Grand Canyon, they tell him to wait in the car while they go for a hike. No one is expecting Guppy to go on his own hike - all over the Canyon. But this isn't just any hike. Guppy is lost and spends the day trying to find his way back to the car. His hike isn't without perils, as he encounters a Rattlesnake, hungry Mountain Lion, a mighty Condor, and some wild Coyote pups. Luckily, a Raven introduces him to many friendly residents of the Canyon, too, like a Deer, a Lemur, a Skunk, a Rabbit and Bats. They all pitch in to help Guppy find his way back after his long and exciting Grand Canyon Adventure.
