Yeah...and then you want them, just like I do.
I loved the Zaunkönigs, in SH3.
Did you ever follow such a fish on cam, along it's searching path?
When target comes closer, you can see it jinking from L to R, constantly adjusting course.
If it misses, and zipps past the stern, it makes a fast narrow turn, and comes in from the other side!
....and it won't miss, this time.
