According to Field, the transition from writing music for an adult rock band to writing children's music was not a big one for the Wiggles. "The Wiggles music isn't all that far removed from what we did in the Cockroaches, just a different subject matter", Field stated. "The Cockroaches sing about girls and love and stuff like that; the Wiggles sing about hot potatoes and cold spaghetti." Moran stated that the Wiggles wrote songs they liked and would listen to, and then made them appropriate for children. They approached simple and relocatable topics, such as food and nutrition, as teachers would in a pre-school setting, with simple melodies that were easy for children to sing and remember. The group sang the same 60s-style pop as the Cockroaches, but with different lyrics, although they were not confined to songs about love and could write about anything that interested and excited young children, which was limitless. The music they chose to write and perform was influenced by nursery rhymes, folk music, and rock songs of the 1950s and 1960s. Page reported, "First and foremost, we're entertainers". The Wiggles captured the interest of children by first entertaining them, and then by presenting them with educational messages.
