Culled from the BBC's "Hidden Kingdoms" series, this amazing double adventure lets you experience life from ground level for two of North America's smallest mammals. Watch as a young chipmunk gathers food and dodges predators in advance of its first winter, then hop along with a tiny grasshopper mouse as it tries to avoid becoming a hungry owl's next meal. Stephen Fry narrates. 43 min. Widescreen (Enhanced); Soundtrack: English DTS HD 5.1 Master Audio; Subtitles: English (SDH); featurette. Also includes a Blu-ray 3D that requires a 3D television, a 3D Blu-ray player, and special glasses to reproduce the original theatrical experience.
