Isaiah has painted the story of Kodjokkodjok (Two Brothers) and Ngalyod, the Rainbow Serpent. A long time ago in the old days there were two men, an older and a younger brother. They were both living at a place called Gamarrkawarn and another place called Marnamarnayi. They went to Kakadu area to get bamboo spears. When they had lots of bamboo spears they went on their way back home and the younger brother saw a possum in a rock. The older brother got it and killed it. They collected sticks and made a fire then cooked the possum on the sand. When the possum was cooking his eyes popped out and rain came down. The ground got soft and then ngalyod (the rainbow serpent) came up and dragged the brothers to where the big billabong was and drowned them. Both brothers became burarr (water goanna).
