King Salmon can be found in the Leisure Park pond or Seon's Food & Stuff. It only takes one hit to kill a zombie with these and it has a very quick attack, but the king salmon "breaks" after two hits. They serve primarily as a gag weapon, but can be devastating in the hands of a survivor since their items never break. Interesting enough, the object has very odd physical properties, allowing it to bounce off of the ground or off of walls at great speed.

Both the fish in the pond and the fish in Seon's seem to be frozen, as Frank picks up a fish and it is not moving, though it moves in the pond. You cannot put the fish back.
You can also blend this item in a blender.
