There are a lot of cooking stations in Hello Kitty Island Adventure. Here, you can find some of the best recipes among them all.
In this guide, we will take a look at how to access the Sewers in City Town for the first time. This Hello Kitty Island Adventure location has a lot to it, but this will cover the initial trek down here, as it won’t be available immediately after you visit City Town.
Quest To Unlock The Sewers
To unlock the Sewers, you’ll need to complete the quest called Above and Below. This quest has its own requirement, which is to complete Tea Time. As expected, this is another quest with its own set of requirements, which you can find below.
- Reach Level 10 Friendship with Usahana
-
Complete Imagination Cafe
- This unlocks at Friendship level 7 with Usahana.
- You’ll also need to complete A Whole New Menu (friendship level three with Usahana) to unlock this quest.
Once all of this has been completed, you can then move on to Tea Time, and then eventually begin Above and Below.
How To Complete Above And Below
Above and Below isn’t too difficult to complete, but there are a few steps involved. Firstly, head to Hello Kitty to begin the quest. While talking to her, she will mention that she wants to meet up with Usahana in City Town.
From here, travel to City Town where you will find Hello Kitty, Chococat, and Badtz-maru waiting at the fountain in the center of town. Talk to Hello Kitty again, and you’ll learn that Chococat wants to study the fog.
This will begin a short cutscene about the City Town fog, but interestingly, nothing happens related to it. Usahana shows up and wonders what everyone is doing, and then everyone will move on. In a future update, something may appear beyond this fog, but for now, you’ll turn your sights elsewhere.
Prepare Boba For Everyone
Before heading to the Sewers, everyone wants to hang out. Of course, it’s up to you to prepare the drinks for the occasion, so you’ll be tasked with making four Unsweetened Apple Boba. The prerequisite for Above and Below is Tea Time, so you should already know how to make this drink. To do so, you’ll need to combine the following ingredients at the Chef’s Station.
- 1x Tea Leaves
- 1x Apple
- 1x Tapioca
The drink isn’t milky or sweetened, so you’ll just need to make this version four times to fulfill this portion of the quest.
After you’ve made the Boba, head to everyone at the park and give all four drinks to Hello Kitty. This will cause everyone to start talking, and Badtz-maru will mention the Sewers. Usahana will then tell everyone about the Sewers; once the conversation is done, follow everyone to the Sewer entrance, which is just south of the fountain where you originally met everyone.
Inside the Sewers, head slightly right and up some stairs until you reach everyone. At this point, there is just one final step in the quest; you’ll need to complete the Underground Introductions puzzle room.
How To Complete Underground Introductions
For the most part, puzzle rooms aren’t required, but Underground Introductions is necessary in order to complete Above and Below. The main mechanic of this room involves raising and lowering the water level in order to place gold cubes on buttons.
The cubes don’t have a corresponding button; you can put any cube on any button in the room.
Below, you can check out the steps to complete this puzzle room.
- Jump into the water, where two cubes can be found at the bottom of the room. These cubes can be placed on the Pink and Blue buttons without moving the water level.
- There is a third cube in the water that you can also grab and temporarily place next to the Blue button.
- Head to the top section and glide south to the wooden platform that touches a pillar with a golden cube.
- With this fourth cube in hand, jump into the water and drop it off near the Blue button. There should now be two cubes on buttons, and two extra cubes nearby.
- Head to the top-left side of the room and flip the switch to raise the water level.
- Swim down to where the two golden cubes are temporarily placed and grab one.
- Swim back to where the water level switch is, and go up the submerged staircase to the left of it.
- Walk across this upper portion and drop the cube off at the Green button.
- Jump back in the water and grab the final cube.
- Head to the top section, directly above the Yellow button. You can’t drop it in the water, so put the cube at the top for now.
- Flip the water level switch one final time and then head back to where you dropped the cube off.
- Grab the cube, and then jump down to the Yellow button, placing it on top.
- Go to the wall with five Shape icons on it. Flip the switch here to reveal the chest and unlock other areas of the Sewers.
Before leaving, be sure to jump down and open the chest, which contains a Green Turtle Shell Backpack.
How To Complete Above And Below
Once you are done with the puzzle room, head back outside and talk to Usahana. This marks the official end of the quest, but after waiting a day, you can then begin Daydreams and Drains. Until then, everyone will disperse, and the quest will be complete.
At this point, you can continue to explore the Sewers. Unfortunately, there is no in-game map of the Sewers but thankfully, the Hello Kitty Island Adventure community has come to the rescue. You can find an unofficial map on Reddit that displays the layout, as well as all puzzle rooms, mailboxes, and other features.
How To Revisit The Sewers
Since there is no map of the Sewers, you won’t be able to freely teleport out of the area. Instead, this can only be done by finding a ladder to the surface or teleporting from a mailbox.
If you’ve already activated a mailbox, you can use this as a point to teleport back in with. You can also re-enter into the Sewer at manholes that are spread throughout City Town. If you run over a manhole and the icon of a cover with a pink arrow appears, you can climb down.
There are some Gudatamas that disguise themselves in a manhole. Once you take a picture of them, the Gudatama, along with the entire manhole, will disappear.
