Sudden, Unexpected Crocolisk Aggression

Objectives
Slay 8 Mortbreath crocolisks at Kea Krak.
 * Mortbreath crocolisk slain x8

Description
Normally, my day consists of catching fish, and then eating the fish I caught, followed by sleeping. Note that I did not include "fight with a crocolisk" in that list of activities.

You look like a handy. Can you go get rid of some of these crocolisks, so I can get back to my regular routine? The crocolisks normally keep to themselves up at Kea Krak, to the northwest.

Completion
Yesterday, we were fishing happily. Today, the crocs just started... tryin' to eat us.

Strange.
