On a high mountain plain lives a lamb with wool of such remarkable sheen that he breaks into high-steppin' dance. But there comes a day when he loses his lustrous coat and his pride along with it. It takes a wise jackalope—a horn-adorned rabbit—to teach the moping lamb that, woolly or not, it's what's inside that'll help him rebound from life's troubles.

For the lamb, life is an upbeat western waltz until his prairie friends tease him about his freshly sheared look. The only one who can set things right is the giant jackalope, who brings sunshine and optimism wherever he bounds.

Writer-director Bud Luckey, a longtime Pixar animator and designer of Toy Story's Woody, found inspiration for "Boundin'" from the Montana of his youth. Starting with the most pathetic thing he'd ever seen—a newly shorn lamb in the rain—Luckey crafted a story told through song. To rescue his sad lamb, he brought in a jackalope, a mythical animal popular in America's Great Plains.
