More than 900 children doodled and coloured to their hearts' content at art activities at the Esplanade - Theatres on the Bay on Children's Day yesterday. Children aged five to 12 took part in a drawing contest, while those aged two to four were involved in a colouring activity. These were part of the Esplanade's Octoburst! - A Children's Festival, an annual arts and culture event that started on Thursday and ends tomorrow.
