For preschoolers who enjoy Barney primarily for his toe-tappin' sing-alongs, here's a program that offers 45 minutes of nearly nonstop music, borrowing from the popular format of earlier videos Barney Songs and More Barney Songs. In this case, the beloved purple dino celebrates the flora, fauna, and all-around fun of the park. The musical collection is a mixture of new and previously aired tunes (from TV's Barney & Friends), compiled for their similar themes of picnics ("Gonna Have a Picnic"), playgrounds ("A Swing Is a Beautiful Thing"), ponds ("Duckies Do"), and parades ("Big Parade of Costumes"). Between songs, learning concepts such as counting and colors and a storybook reading of the classic tale "Lion and the Mouse" cap this woodland excursion. Though filled with predictable pleasures, the film lacks the creative sizzle found in the jazz-rock-folk medleys of More Barney Songs, and Barney's new voice-over may take some getting used to.
