The Primordial Thicket (追憶の原生林^?, lit.: "Primeval Forest of Recollection") is the sixth and final area in Pikmin 4. It is set in a large and muddy autumnal forest. It contains 15 surface treasures, 74 cave treasures, 8 rescues (5 castaways and 3 leaflings), and 3 Onions. There are 7 caves in total, with one being a Dandori Battle cave and three being Dandori Challenge caves. This area has × 7,750 worth of treasure, of which × 2,580 is above ground.

Plot

After the Rescue Corps reunites Yorke and Don Bergman, Don Bergman remembers seeing a dog-like creature drag their partner Nelle deeper into a forest. Yorke upgrades the S.S. Shepherd so that it can scan this area.

Right as the rookie Rescue Officer and Oatchi set foot in the Primordial Thicket, they see Louie and Moss holding an unconscious Nelle. They follow Louie into a cave where he tries to turn Nelle into a leafling, as he had attempted with Yorke. The process fails again and Louie challenges them to a Dandori Battle. Upon defeat, Louie runs away, abandoning Nelle as well as Moss. The morning after Nelle is rescued, she informs the crew that to cure Oatchi's tail, they will need cells from a non-leafling dog.

An entry in Louie's voyage log reveals that he found a large dog called the Ancient Sirehound, whose den is in the Cavern for a King. When the Rescue Corps duo confonts Louie at the bottom of the cave, he climbs on top the dog which proceeds to attack. Defeating the Ancient Sirehound yields Louie and the dog's collar. Yonny extracts some of the Ancient Sirehound's cells from the collar and makes a cure that reverts Oatchi to normal, allowing everyone to leave PNF-404 safely.

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 rush to grow potted mushrooms. His jump is then needed to cross the mushrooms and access the ledge with Louie, Moss, and Nelle.
