The bullocks are looking for water and they went to the wrong kapi - into the mud and they got stuck in the mud. The stockman was looking around everywhere for that bullock and found them in the mud and pulled them out.

This is also a bible story. This is about people stuck in the wrong place for doing bad things and living a bad life. It is also like Noah-time. Noah's ark. Noah took some animals on that boat to save them. All the people except Noah lived a bad life and got washed away by that big flood.
