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.
