When Bear's old truck needs a new headlight, there's just one thing to do - organize a road trip to Elephant's junkyard to find a new one. And a road trip wouldn't be complete without friends. Bear rounds up Rabbit, Mouse, and Donkey to come along. Some take a little coaxing-Rabbit doesn't want to miss lunch, and Mouse worries about what might happen along the way-but the ever-positive Donkey takes the lead as the four friends head out. What follows is a day of adventure, and misadventure, in the charming world of Whiskers Hollow, where the inhabitants zip around the tree branches in their unique vehicles and treasure is found in the most unexpected places.
