If you catch a Riptide Mouse, you will be washed back to the Jungle of Dread. Be sure to check your location, to avoid the Swarms of Pigmy mice stealing your precious Vanilla Stilton!
Unlike the Forbidden Grove, this location is never "closed"; you can travel back right after you catch a Riptide mouse. However, this is not recommended, especially during high tide.
If you prefer to stay in Balack's Cove through medium and high tide, you can unequip your cheese (by selecting the cheese you're already using through the camp page; a red DISARM should appear as you hover over it). This prevents you from catching any Riptide mice.
Or, you can craft Empowered Anchor Charms with 1 Flawless Orb + 1 Scrap Metal + 40 Charmbits; equipping these gives you a small power bonus, and you won't be affected by catching Riptide mice. This option can be quite expensive though.
There are many new mice here; most notably:
The Derr Lich mouse, which drops Bottled-Up Rage
The Nerg Lich mouse, which drops Raisins of Wrath
The Elub Lich mouse, which drops Pinch of Annoyance
With these loot items you can now craft Vengeful Vanilla Stilton cheese. There are again two recipes:
It is recommended that you use the second recipe if you have Super Brie to spare, as the loot items can be pretty tough to acquire.
This cheese is used to attract the Balack the Banished mouse. Arm the Ancient Box Trap, and cross your fingers.
Good luck, you'll need it! And again, beware the tides!
You need to be Lord/Lady to enter the next area. Meanwhile, you can go back to catch the mice you missed, or try collecting the ingredients and crafting the following powerful, but hard-to-acquire trap components:
Molten Shrapnel Base
The power of the Monolith base, and the luck of the Aqua Base combined! The downside is its Extremely Stale cheese effect; but that just means more Stale Cheese to use, right? The recipe is as follows:
1 Dragon Ember (loot drop in Dracano)
200 Scrap Metal (loot drop in Catacombs; could take a while!)
