This is it, folks. Welcome to the final area of Pikmin 4. This poison-pocked landscape will prove resistant and inhospitable, but it's the only place left to collect treasure. You'll find Flarlic, Pink Onion, and all sorts of fungal-looking enemies here.
The treasure counter will be misleading, with nearly half of the treasure to be found all hiding within a single cave only accessible by progressing in the main story. Don't worry if you don't get it all; you can always come back after to collect the rest. But if you prefer to be a completionist on the first go, you may want to get everything you can before pursuing Louie.
Be Advised: This guide contains spoilers for the end of the game, starting at the Cavern For A King section and beyond.
Primordial Thicket Surface Treasure Locations
The landscape here is full of muck you can't swim through, poison that will hurt you and your Pikmin, and dangerous creatures. Bring lots of Ice, White, and Red Pikmin to deal with the dangers here. You'll need 100 Purple Pikmin for one of the treasures, too.

Subterranean Swarm Treasure Locations
Despite how far into the game this one is, it's a fairly bog-standard cave experience, with traditional underground aesthetics and insect enemy types. There's no particular advice to give here.

The Mud Pit Treasure Locations
Remember how lovely the resort cave was in the previous levels? This is like that, but less fun. It's dark and muck covered. Don't bother with Blue Pikmin, they won't be good at handling the muck. Bring Winged Pikmin instead.

Cavern For A King Treasure Locations
This is it, folks: The final cave in the game and the only way to save Oatchi from illness. If you can't find this one on the map, progress with the main story and beat Louie in the Dandori battle. This will uncover the previously hidden entrance.
You don't have to go through the entire cave in one go. Sublevels 6 and 12 have exits, and you can return to the surface at any time to resupply.
Since nearly every single room is just a boss arena, we'll be omitting the area maps for this cavern and compressing every treasure into one large table.
