On January 9th, 2017, a radio personality by the name of Rella Rivera was with her young daughters shopping inside of a Costco when they encountered William Va'ana.  Va'ana worked as the cashier. The little girls shouted "Maui", in reference to the memorable character from the film Moana. 
During the excitement, Rivera took footage of Va'ana playing the part for the two kids. The video has since gone viral.
