On this 2007 Wiggles outing, the beloved Australian group presents more kid-friendly tunes. Highlights of GETTING STRONG! include the breezy "Wiggle and Learn," the silly "Swinging on a Swing," and the jaunty "First in Line," tracks that exemplify the appeal of the lighthearted, color-coded entertainers. In addition to the four Wiggles members, the record also features other fun characters, most notably Captain Feathersword and Dorothy the Dinosaur (see "Dorothy's Introduction").
