Pursuing Terrorclaw

I've caught every kind of fish that lives in the marsh, but there's one that eludes me. Sure, I've caught eels and mudfin frenzies. But the last time I was out on one of the islands in Marshlight Lake, I hooked a gigantic bogstrok that snapped my line and got away.$B$BTerrorclaw, he's called, and I won't rest until he's dead. He's too big for any fisherman to catch, so I suppose we'll just have to kill him the old-fashioned way.
