It’s time to get through the final stretch of Humphrey’s area. After presenting Humphrey with the Slimy Keycard, you’re transported downstairs into an area with a picnic basket and treats to heal the party. Mari isn’t there, but I suggest saving and making sure everyone is good to go because you’re in for a rough stretch.

After saving, continue north where you’ll encounter Sweetheart. She’s confronted by Molly, Marina, and Medusa, the three slime girls running experiments inside of Humphrey.

After their confrontation, Sweetheart storms off, as she’s done with all three Slime Girls, but this time, she leaves the debt for Omori and friends to pay.


After calculating how much Sweetheart owes the Slime Girls, they come up with a total of 1,000,000 clams. Unless you’ve been grinding for days, you won’t have 1,000,000 clams at this point.

The Slime Girls then grab Kel and threaten to kill him before he frees himself. That’s when Hero decides the only way out is by fighting.

The battle between Omori’s group and the Slime Girls begins.

There is a mechanic to this fight, but it doesn’t come until you get the Slime Girls down to a certain HP. However, if you want to make quick work of this fight. Have an item ready like confetti to make the party happy. Alternatively, you can use Aubrey’s Team Spirit ability to make her friends happy. Have Kel use Annoy (or use an item) to make the Slime Girls angry.

With the party happy and the Slime Girls angry, you’ll be able to hit non-stop moving attacks while their attacks barely register.

Once you get the Slime Girls down to a certain HP, they switch the party’s juice and hearts, so make sure you’re using Hero to keep everyone capped off.

Also, make sure you make everyone happy. I couldn’t get Hero’s emotion changed as fast as I was doing damage, so he was taking normal damage from their multi-hit attacks. If I had changed his emotion to “happy,” he would take dull damage.

Continue the assault on the Slime Girls. Using multi-hit attacks are best.

Have Aubrey use Headbutt to keep their defense down.

Once the Slime Girls get low HP, they’ll start using different concoctions at the party. One will drain the entire part of their juice.

Another one lowers their stats.

It gets nail-biting near the end; you’ll want to possibly move Kel to a backup healing role by keeping everyone’s juice and hearts up along with Hero.

One of their final concoctions changes the party’s emotions. However, it’s not worth trying to get everyone back to happy. One more Hack Away from Omori at this point should take them out.


Once you defeat the Slime Girls, Humphrey starts to rumble. Apparently, when Sweetheart didn’t pay up, his hunger was not satisfied. He claims to have killed Sweetheart off-camera before opening his mouth and consuming the Slime Girls.

Once you have control of the party again, Switch to Aubrey. You can’t go into any of the Slime Girl’s rooms; the only way you can go is down.

Smash your way through any Humphrey’s blocking your path.

Once you make it back, you can’t get to the save point. You’re surrounded by Humphreys.

The battle with Humphrey begins. First, you’re fighting off his taste buds (or what I assume are his taste buds).

I used my normal combination of making my party members happy and making Humphrey angry to make short work of them.



After taking out Humphrey Grande, it’s time to battle through Humphrey’s stomach.

When you’re devoured, you get hit with party-wide damage, so make sure Hero keeps everyone topped off.

Just like before, make Humphrey angry so you can hit moving damage on him.

Omori’s Hack Away does wonders while you’re still building energy.

Every time you deal a certain amount of damage to Humphrey, you move deeper and deeper into his stomach.

However, if you keep his stomach angry while keeping the party happy, it shouldn’t do a lot of damage.

Keep up the attack with Aubrey’s Headbutt, Omori’s Hack Away, and Kel’s Rebound. Keep Hero on healing duty.

After the battle, you end up in Humphrey’s mouth, where you engage in the final battle with his uvula.


However, you should be able to take it out in one hit. This is when Humphrey is finally defeated.


After Humphrey’s defeat, you’re shot out of the whale along with the T and W keys.

The group will remember that they’re searching for something. They have long since forgotten Basil.

When you pick up the keys (make sure you’re on Omori), you’ll see more holes in the ground.


Looking through each hole will give you ominous images.

After picking up the keys, go down the hole where Humphrey disappeared. You’ll enter a story area. Just follow the path where a voice will narrate every time you hit a certain point in the water.

When you get to the end, you’ll see the same window you saw when Omori and Mari were swimming around the lighthouse area.

After the window disappears, the SOMETHING creature appears on the wall.

Clicking it will show you the hangman screen. I’m still missing two keys.

After clicking on SOMETHING, you’ll be back in the Neighbor’s Room. If you need to get back to the Hangman page, you can click on the open shelf in the Neighbor’s Room; at this point, I’m going to grab the keys I don’t have.

If you need to save, you can head down to the Forest Playground to Mari’s blanket.
