Wal-Mart Vision Center hosted its second annual Back to School Sponge Bob Coloring contest and announced its winner Wednesday. Vision Center manager Karen Kittle presented Leah Robinson, 9, with a Sponge Bob book bag filled with school supplies. She also received a bouquet of balloons and an assortment of educational games. Many children participated in the event and the contestants were narrowed down by the associates of the vision center who chose their six favorites. Customers then picked their favorite of those six. Robinson is entering the fourth grade at Trinity Christian Academy and is shown with her mother, Kathy (left) and Kittle. All participants in the contest will receive small prizes.
