Overview

Post-game dungeon featuring Sumo Onigiri as the only food item found on the ground.
The player can bring items, but it can be cleared without bringing any items thanks to Sumo status.
The dungeon has lots of items buried in wall tiles, since Sumo status allows digging through walls.
Overall, it's basically just a place where players can visit to learn how Sumo status works.

Strategy

General

Sumo Status

Occurs when Max Fullness reaches 150, and is canceled when Fullness depletes to 120.
Sumo status boosts Shiren's attack power by 50%, and also increases max HP by 50.
In addition, Shiren can also dig through wall tiles without penalty, and becomes immune to traps.
However, fullness depletion is doubled, and movement effects like Vaulting Staff are nullified,
so Sumo status isn't strictly all positive effects.

Sumo Onigiri

Nigiri Baby does not appear, so Sumo Onigiri is likely going to be your only food source.
It's hard to maintain Sumo status if you don't bring items like Peach Club or Shield of Sating,
so aim to only activate Sumo status when you need the additional HP and attack power.

Floor Guide

This section assumes that the player isn't bringing any items into the dungeon.
Overall, the monster table is similar to Serpentcoil Island, but condensed to 20 floors.

1F

Enemies are weak, so linger until the wind blows to farm experience points and item drops.

2F

Pumphantasm (23 HP, 16 atk) appears, so consider activating Sumo status if you lack a shield.
That said, if you are able to linger without entering Sumo status, that's generally a better option.
If you decide to activate Sumo status, go ahead and advance to the next floor.

3-5F

Enemies are based on Serpentcoil Island 5-9F along with Scorpion (37 HP, 14 atk) on 3-4F.
Hoppin' Hitter (32 HP, 22 atk, 15 def) and Mid Chintala (45 HP, 23 atk, 10 def) both hit hard.
Fire Ninja D (28 HP, 18 atk) and Water Ninja D (24 HP, 15 atk) can either grill or rot Sumo Onigiri,
so don't linger around on these floors.

6-9F

Enemies are based on Serpentcoil Island 10-15F (Underwater Passage).
Bowboy (45 HP, 17 atk) and Crossbowboy (55 HP, 20 atk) appear on 6F - collect arrows if possible.
Masked Samurai (47 HP, 18 atk) appears on 6F, and Mudkin (70 HP, 5 atk) on 7F, but they don't overlap,
so you won't be able to hunt Lv3-4 Mudkin monsters to level up in this dungeon.

10-13F

Enemies are based on Serpentcoil Island 16-19F (Kibanuma Marsh).
The only dangerous enemy is Pop Tank (90 HP, 20 atk) since it can grill your Sumo Onigiri.
Otherwise, enemies shouldn't really be an issue as long as Sumo status is active.

14-18F

Enemies are based on Serpentcoil Island 20-23F (Firespew Mountain), hallways are dark from 15F.
Lv2 Ninjas appear, so don't forget to protect your Sumo Onigiri against Fire and Water ninjas.
Super Gazer (66 HP, 30 atk) also appears, but losing items to hypnosis isn't that big of a deal here,
since you can just rush to the stairs for a few floors until you clear the dungeon at this point.

19-20F

Enemies are based on Serpentcoil Island 25-26F (Mount Jatou), and hallways are still dark.
Try to maintain Sumo status until the end on these last 2 floors, and focus on finding the stairs.
Porko (65 HP, 36 atk, 18 def) throws Porky's Rocks that deal 20 damage within a 5 tile radius.
Dartingfrog (75 HP, 40 atk, 28 def) pulls you closer (5 tile range) and attacks on the same turn.
Daze Radish (80 HP, 37 atk, 27 def) throws Confusion Grass within a 2 tile radius.

Consider hunting a Menbell (100 HP, 30 atk, 30 def) on 19-20F for the monster notebook,
since it's somewhat uncommon to see it spawn naturally in a dungeon.
