3 years & up. 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. 24 pages.
