Walkthrough Guide:
The guide for this location is pretty straight forward as there is not much to do here other than keep hunting the mice.
1. Collect 4 Splintered Wood to craft Dehydration Base
There are 2 mice here that drop the Splintered Wood:
Both can be attracted using the standard cheese, Swiss Cheese should be enough.
2. Craft Dehydration Base
Once you have got the 4 Splintered Wood, you can now craft the Dehydration Base.
Here is the ingredient list:
4 x Splintered Wood
1 x - Sold at Harbour - General Store for 22,330 gold
213 x Salt - Sold at many General Stores, including the one at Harbour
You might also want to upgrade your trap if you have not. Swiss Army Mouse Trap or NVMRC Forcefield Trap might be a good choice unless you have better trap.
3. Catch Cyclops Mouse
Adventure: Catch a Cyclops Mouse and find the Great Gnarled Tree Map Piece
