Ro, ro, the rattlin' bog, the bog down in the valley-o! Joining Barefoot's singalong collection, this rollicking traditional Irish tune sung by a traditional Irish band explores an Irish peat bog where a rattlin' (Irish slang for "wonderful") tree contains a rattlin' nest, which contains a rattlin' egg, which contains a rattlin' bird . . . all the way down to a seed of a brand-new rattlin' tree. Includes notes on Irish peat bogs and the creatures that live there, as well as plant and animal life cycles. Includes QR code access to audio and video animation.
