Long, long ago, there lived some great fishermen who were unable to catch any fish because something was stealing their bait. So they set off to the sea to hunt it down.
Bursting out of the water, the octopus clung to the waka tossing the people everywhere. So Kupe bolted out of his seat and slashed at it as everyone on this waka let out tremendous screams. The final slash at it killed it.
He hoped it would never happen again.
