Dandori Challenge 1
This Dandori Challenge can be accessed by building the large clay bridge near The Maple Bridge base, and jumping up to the elevated entrance with Oatchi. Building the climbing wall near the Puffstool area can help you reach the area, but Oatchi is still needed and cannot access the area through this method.

Dandori Challenge 2
This Dandori Challenge is across a shallow mud puddle near The Autumnal Gully base. It can also be accessed through a tunnel on the other side of the map, if the map is instead traversed clockwise.

Dandori Challenge 3
This Dandori Challenge must be accessed by pushing a Cardboard Box down in the Beckoning Mannequin area, past the dirt wall near The Autumnal Gully base. To do this, White Pikmin are needed to destroy the poison geysers. Destroying them will guide the Pikmin toward the box, and they will lock on automatically. If you do not throw enough White Pikmin (10) to push down the box, you can throw Pikmin from the other side of the wall once the poison has been eliminated. From there, Oatchi is needed to jump up the slopes to the cave's entrance across the box.

Dandori Battle
The area's Dandori Battle cave, Final Battle, is located in the northeastern part of the map. It can be accessed by using Oatchi's charge to grow Potted Mushrooms. His jump is then needed to cross the mushrooms and access the ledge with Louie, Moss, and Nelle.
