The painting depicts a place near to Tjukurla, Nerida's mothers country. She cannot say the name of this place, as it is the place of an important Tjukurpa, where the Porcupine pushed that big Perentie lizard out of the way.
The Porcupine was really angry, jealous, because the Perente had been loving that Porcupine's wife. He went looking around for that Perentie, found him and pushed him out of the way, blocking his path. The porcupine did not want him to pass through.
The porcupine and the perentre became the mountains in the country, the are still here now.
