Simple movements were developed by their choreographers, including Leeanne Ashley, to accompany each song because, as "The New York Times" reported, they believed "in the power of basic movements to enchant young children". According to reporter Anders Wright, they intentionally made mistakes in their dance moves in order to identify more with their young audience. The group incorporated more dancing into their performances after the birth of Field's oldest daughter in 2004. "So Wiggles have kind of become a bit more, dare I say, girly. Dorothy (the Dinosaur) does ballet now and we dance as well a lot more than we did", Field reported. In later years, corresponding with Field's developing interests in acrobatics and gymnastics, they added these elements to their stage shows, including, as Field reported, hiring several world-class athletes such as former trampoline champion Karl Shore. Watkins, whom Paul Field called "a dancer of many disciplines", was initially hired as a member of their troupe and referred to herself as "mainly a dancer".
