According to Sandtail lore, there used to be a city that once sat on the far east cliffs of the desert until the arid soil cracked and shifted, causing the city to slide into the water. Once thought only to be a legend, it appears now that the story is true – as the city has been spotted under the water!
In order to access this new area, you have to at least be the rank of Count and have already rebuilt the cartographer in the Muridae Market – where you will purchase the “map piece” for the new location. Buying it during the first week of the release allows for hunters to purchase it only with gold (228,000), but after the first week, it will require 90 molten glass to go along with the gold price.
Open your map to the Rodentia section and travel to the Sunken City. You need a strong hydro trap, preferably the Phantasmic Oasis Trap, to hunt here. Traps weaker than this can work, but at reduced effectiveness obviously. Take your time to get the POT because this area is permanent content; it’s not going anywhere.
To start off, you are reduced to only catching a few mice that don’t drop very much loot (or gold for that matter). What they do drop are oxygen canisters. You use these to dive down into the water to explore the ocean in your submarine and catch more powerful mice/fish.
You need lots of Oxygen Canisters to dive. With Gouda/SB+ armed, you will only attract 4 mice. Gouda attracts 3 of them very well, but the Hydrologist mouse, while occasionally being lured to your trap with Gouda, is almost an exclusively SB+ only mouse. Using Fishy Fromage cheese will greatly increase the amount of canisters you collect, but initially, you cannot craft or buy this cheese unless you donate to the devs. You need loot you find underwater. Naturally, your first few days here are going to be a slog (think Claw Shot City!!), but it will get better once you have access to more loot to craft the new cheese.
- Sunken City (Docked) (All mice CAN drop Oxygen)
- City Noble (Gouda/SB+/FF)
- Sunken Citizen (Gouda/SB+/FF)
- City Worker (Gouda/SB+/FF)
- Hydrologist Gouda/SB+/FF – extremely rare with Gouda)
- Enginseer (FF only mouse)
- Elite Guardian (FF only mouse)
- Clumsy Carrier (FF only mouse)
- Oxygen Barron (FF only mouse)
The Oxygen Barron can drop up to TEN canisters at once. For the others, the maximum I’ve seen is four.
So how many oxygen canisters should you loot before making your first dive? Well, it depends on how far you want to go, but it is advisable to have enough oxygen on your first dive to make at least 50 hunts underwater. Most people I have seen have collected enough to get over 100 for dive #1. More on this below.
Below will give you an overview of what you need to do in order to dive, and to guide you through your first run, what to expect, what to do from an over-arching view, etc.
- 10 Oxygen Canisters are needed to dive into the ocean
- After this, ONE oxygen canister is needed PER HUNT underwater
- Example: You’ve hunted in the Sunken City until you’ve looted 30 oxygen canisters. Clicking the “Dive” button on the HUD will use 10 of your canisters, leaving you with 20 leftover. You thus have 20 hunts underwater until you collect more canisters. If you abort, you lose your progress (and of course any oxygen canisters you’ve already spent, such as the first 10). Because of this, I recommended that, for your FIRST DIVE, you at least wait until you can hunt 100 – 200 times at once. This will be a tad boring catching the same several mice over and over, but it’s worth it in the end.
- Each mouse you catch underwater will allow you to explore 30 meters further into the ocean. Each time you fail to catch a mouse, you only advance 10 meters. Failing to attract a mouse underwater does not move your progress, but it does waste oxygen. Because of this, it is advised to use Super Brie underwater.
- Equipping an Empowered Anchor Charm (EAC) slows your diving progress. This is extremely beneficial in loot-rich areas (like the Sand Dollar Sea Bar). Instead of moving forward 30 meters, you only move forward 10 meters. EACs can be crafted or purchased on the marketplace. Each location below has my recommendation on the EAC usage.
- Each section you encounter is randomly generated when you dive. This also includes the length of the zone. Zone lengths are as follows:
- 250 meters
- 500 meters
- 750 meters
- 1,000 meters
- 1,250 meters
- 1,500 meters
- 1,750 meters
- 2,000 meters
I have never seen an area longer than 2,000.
- Left-clicking on your submarine will show you the next 4-5 zones. This will give you a sense of what you’re about to encounter.
- Using Fishy Fromage underwater will result in a Fail to Attract. Only use it in the Sunken City when not diving.
- When diving, you will collect loot from mice that you catch, hopefully loot that be used to make more Fishy Fromage.
- Brined Curds, a necessary ingredient in crafting the Fishy Fromage, can be purchased from the general store for 500 gold each, or looted (in very generous quantities) from predator mice in either the red danger zones.
- The same loot to make the cheese is also used to make the new traps. Don’t worry so much about this at this point because the new traps are a long ways off (because Sand Dollars are not dropped in bunches).
- Sand dollars are the “currency” of this location (alongside regular gold) and are found underwater, and they are found in every section, but they are not “regular” drops. In the tables below, check out what mice drop them and where they drop them.
The following are two recipes needed for crafting the Fishy Fromage. After your first initial dive, you hopefully will quite a lot of loot to craft this cheese, so your oxygen canister hunt will go a little more rapidly.
|Fishy Fromage (2 pieces)|
|Recipe can be unlocked by:||Capture a Mlounder Flounder mouse|
|Damaged Coral Fragment||3||Loot|
|Total||0 – 2,000|
|Fishy Fromage (3 pieces)|
|Recipe can be unlocked by:||Capture a Mlounder Flounder mouse|
|Damaged Coral Fragment||3||Loot|
|Magic Essence||1||Crafting / Loot|
|Total||0 – 2,000|
Each time you dive, you enter a different part of the ocean. The locations are randomly determined when you click the dive button, so it’s somewhat difficult to plan a trip before you actually dive.
For maximum attraction, SB+ should be used underwater. Gouda works and has decent attraction, but remember, it’s not 100% (or 99.9% like the devs say). For certain areas underwater where loot is not plentiful, Gouda might be a better option as to not waste your SB+, and save your SB+ for resource rich locations like the Sand Dollar Sea Bar and Pearl Patch. This is obviously a personal preference only – you are free to hunt how you see fit.
Initially, you will want to make shorter dives, rather than longer, massive dives, if you do not donate to get Fishy Fromage, preferably 100-200 hunts at first. Please note that every time you dive, you lose 10 oxygen canisters off the top, so more short dives is less efficient than longer, more massive dives. But without Fishy Fromage initially, it is going to take a long time to collect enough oxygen canisters to have a decent dive. Pace yourself and build up.
IMPORTANT NOTE: You do NOT lose your progress underwater if you simply travel to another location. When you return to the Sunken City, you will continue your dive at the same location. If you click the “return” button on the HUD, however, your dive is OVER and you return to the dock area of the Sunken City. This is to prevent any loopholes of collecting more oxygen at the surface while you’re diving. The only way to collect oxygen while submerged is to come across an Oxygen Stream, where mice drop canisters as loot, or perhaps get a reward from Larry/the devs.
For subsequent runs, collect more oxygen. This is natural because as you continue to hunt underwater, you build up supplies and you get more and more efficient at hunting for oxygen canisters on the surface. Your second run should strive to reach well into the second tier of zones, anywhere up to 12,000 meters. You’ll need 450 oxygen approximately to hit 12,000 meters if all goes well, but again, this is simply an estimate because every dive is random.
The further out you go, the more profitable the zones are in terms of gold and loot. But collecting 450 oxygen canisters isn’t necessarily fun.
One point of strategy that is commonly asked is when and how to use the Water Jet Charms. When you catch a mouse with this charm equipped, you move forward 500 meters instead of 30. At first this may sound silly, but look below at some of the areas, most notably the Shallow Shoals, Sea Bottom, and Murky Depths: these locations do not provide consistent loot, and the loot that you DO get is very scarce. While the points of these mice are nice, you’re here to get loot and rewards.
So, when should you use the Water Jet charm? Well, it costs 3 Sand Dollars plus 50 coral, 50 barnacles, and 50 mouse scales. I would personally use them when you are faced with a 500 – 1000 meter section of low-loot areas. Obviously, this is all dependent upon your situation. Underwater, not every situation is the same because everything is random, so there is not always a one-size fits all answer. But covering large expanses of low-loot areas in one or two hunts is better than 25-50 hunts.
It should be noted that Water Jet charms are almost a necessity to reach locations that are extremely far out, unless you spend lots and lots of time collecting oxygen. Again folks, it’s all about balancing expectations and reality. If you want to travel 20,000 meters, do some quick math. If you caught every mouse on your journey and never missed one nor had any FTAs, you’d have used 667 oxygen canisters! As you can see, that’s a large amount of oxygen, and thus why it’s advisable to use Water Jet charms from time to time.
It’s all about what YOU want to do and what YOU want to collect.
UPDATE: During the July 4 Feedback Friday, the devs stated that there were MORE THAN 20 underwater locations! So….a lot more than what we have found here! I am out of town July 5 and 6 and will not be actively hunting or checking the site, so any feedback on additional areas people find, please let me know! 🙂
Special thanks to Trey Tate, Keith Farhall, Calvin Lee, Marin Domjanovic, and the rest of the MHCC for posting all their findings in depth on the MHCC Facebook page!!
The tables below give the mice and loot you will find in your random dive locations (for information on how to dive, scroll below). Please note this is a work in progress and we feel we still haven’t discovered all the locations yet (because there are still a lot of mice missing)!

0 – 2,000 Meter Locations
The Rocky Outcrop is the first location you’ll encounter that drops Barnacles in large quantities. Just hunt normally without any EACs unless you need to replenish your supply of Barnacles.
2,000 – 10,000 meter locations
The default zone for the second “tier” of underwater locations, like the Shallow Shoals before it, your goal here is to hunt normally or just skip it entirely.
10,000 + meter locations
There are oxygen streams underwater where you can catch mice that drop oxygen canisters! You can now replenish your oxygen supply! I will create a location table for them shortly.
Note: I realize there are more locations! I have not updated this guide for this page in a few months, but plan on getting the 20,000+ meter locations up soon. Part of the reason is that I like to hunt these areas myself before offering an opinion on them – and after a few long dives around 20k, I went back to the Burroughs Rift area.
While I gather details on the other areas that are deeper, including the ever-pressing issue of gathering predatory processors, check out the official MH Wiki for basic information on these areas.
