Box turtles are done, but I did some searching around before it was over and trying any other grade other than 3 there by horizon provided zero box turtles. I know you can spearfish the by humblehearth. Also, I tried topwater frogs which vespers chart says they favor, but that proved zero bites as well. It's hard to single them out unless you have a ton of rat tails since they share the same sweet spot as river crabs (which npc decently so it's not all bad).
