Between 1999 and 2003, to test the group's appeal across cultures, Warren used one of the Wiggles' CDs as an educational tool in a village near Madang, on the north coast of Papua New Guinea. She found that the Madangese children were able to relate to the group's songs, and that they were able to sing along and participate in their simple choreography. Although the Wiggles' recorded and performed songs, dances, and musical styles from different cultures and languages, the Wiggles did not find that adapting their music to non-Australian cultures was necessary to reach children in other countries. As Cook stated, "... Toddlers don't have the same hang ups as adults". The Wiggles recognised that as long as they spoke at the same level as their audience, their Australian accents would not matter, and that young children were able to adapt to a variety of contexts and to different pronunciations of common words, no matter where they resided.
