The artist has painted a dreaming story from his country of Bopilinymarr, east of the Cadell River, in Central Arnhem Land. The story was told to Banggala by his grandfather when he was a young lad, living on Croker Island. The old man showed Banggala how to make the fish trap using a special type of grass called munbalarr. It is the same grass that artists still use today to paint rarrk or cross - hatching designs on their work. The fish traps were placed in creeks, channels and river mouths, catching fish such as barramundi, mullet , bream and catfish.
