2. Toxic Spill

Power Type: Hydro
Minimum Rank: 9heroHero
Minimum Recommended Trap: Ancient Spear Gun
Optional Objective: Get the S.U.P.E.R. Scum Scrubber Trap

Large Waste BarrelLab TechnicianThe Toxic Spill is an area unlike any other. It is open to all ranks starting at Hero level. However, Heroes can only hunt here during a very limited time. The pollution levels rise and fall, and when they rise above Hero level, the minimum rank requirement to enter is Knight. After a while the level will rise again, and then only Lords/Ladies and above can enter, and so on.

In a nutshell, this is what happened: The experiments in the Laboratory have mutated some mice by contaminating them with hazardous materials. Some of these mice are so strong that only the most experienced hunters with the very best traps stand a chance to catch them. Washing away the contamination requires lots of water, which is why you need to use a Hydro type trap in this area.Rancid RB Potion

The cheese of choice is Rancid Radioactive Blue Cheese. There are 3 different ways to obtain it, 4 if you count the Marketplace. You will need regular Radioactive Blue Cheese and maybe Radioactive Sludge as well, depending on which method of obtaining you go for. For those with lots of SB+ to convert, there is also Magical Rancid. This cheese can attract high level Spill mice even in lower levels, where these mice usually are not present.


Once you’ve flung yourself into this world of slime and neon goo, just keep sounding the horn. Gather as much Crude Pollutinum as you can. Once your barrel is full, you should start refining it by clicking the “Refine” option on the HUD. Careful though, while you refine the mice can steal your hard-earned Pollutinum if you are unable to catch them! After successful refining, you may use the Pollutinum in various crafting recipes. Once you’ve gathered everything you need from the area, you can use it to craft Empowered Brie and Empowered SB+. They behave just like the regular varietes, with the exception that they give your trap a power boost. These are the first types of cheese that actively help with catching the mice.Soapy Suds

If you happeMutant Mongreln to use Rotten or Super Rotten charms, you can collect Soapy Suds, ingredient of the Polluted’s nemesis, the Soap Charm. These can help you in securing your Pollutinum as you refine it, making it impossible for the mice to steal it, even if you fail to catch them. You also need lots of Soapy Suds to craft new Bases as well, though. So maybe going for the Charms straight away is not advisable. Of course, before you can craft the new Bases, you first need the Blueprints. These, as well as several other interesting things, can be looted from the mice. Canister Rings are also worth mentioning, as they can be used in increasing the size of your Crude Pollutinum collecting barrel.

toxic_scrapSludge SoakerSince thRefined Pollutinume mice of the spill are somewhat tough, especially if you enter the moment you’re admitted, it may be beneficial to try and hunt with a rather powerful/lucky charm instead of breaking out the Rotten Charms straight away. Since the most powerful mice go back into hiding when the Spill level falls, that seems like the most logical time to take off a little of the edge of your trap by applying lesser charms. Of course, this piece of strategy won’t do you any good if you’re of Hero rank.

The reason why obtaining the S.U.P.E.R. Scum Scrubber Trap is optional is the time and effort needed to acquire it. If you have time on your hands, it certainly is an upgrade to what you’ve come across so far. However, if you are ready to move on in the storyline, you may do so without this trap, and you’ll still be fine. Chances are that by the time you can acquire the trap, you will already be close to the Slushy Shoreline or may have already crafted the Steam Laser Mk. I instead, which is comparable in stats. In the end, the Toxic Spill is just a sidequest.

Soap Charm

* Help clean up the Toxic Spill once your rank allows it.
* Hope for rare loot drops.
* Use stronger charms at higher levels and switch to (Super) Rotten Charms once the Spill falls to lower levels. Collect Soapy Suds.
* Refine your Crude Pollutinum once your barrel is full.

      So far it doesn’t seen that complicated. I’ll probably write a first overview of my experience at the end of this spill.
      Thanks for your interest though ๐Ÿ™‚

    MozKa, I’m a Duke so you suggest I use the Soapy Charms first? Then shift to the Super Rotten Charms when the lower ranks come in? Which rank do you suggest changing to the Super Rotten? Thanks for your input and this guide.

      Yeah, the Soap Charms are ment to be used during the high ranks. But I’d wait and pair them with the Washboard Base, because that way they are super effective!
      I’d switch to Super Rottens at Knight rank if you don’t have lots, at Baron/Lord rank if you have quite a few.

    Mozka, can you only catch the mutated behemoth mouse when the toxic spill is at archduke? or you have to be an archduke to catch him?

      you can only catch it when the toxic spill is at archduke. After the spill goes into grand duke, the mutated behemoth will be gone and you will have to wait for the next toxic spill to be able to catch it.

      Yes, both. The Mutated Behemoth is only around when the spill is at Archduke level, and in order to hunt there at that level, you have to be an Archduke.

    Thank you. Would you tell me which is the best setup to catch him?

      Your best Hydro trap, your strongest and luckiest base, and a strong charm. The stronger the better.
      The Washboard Base combined with Soap Charms or even Super Soap Charms is a good choice, although now the Mino Base has surpassed Washboard, if you have that yet.

    Hi, I stopped playing MH for a few years and only clicked back at the app a few days ago. Feeling a bit lost as I forgot everything that was done and what stage of the journey I was at. Your walkthrough is great but I still trying to figure out where I left off from that few years back. Still feeling a bit lost. How do I find you on FB?

      I added my FB profile link to the “Introducing…” page of the guide ๐Ÿ™‚
