The Vast Plain (N3) opens with N2 after the Axe cuts the North tree. Use the finder below for every Gray, Red, Green, and Blue chest, all eight Musical Coins, and exact room-map links for Day/Night plus each map variant—starting with the Gray Chest Green Tablet that opens the West with N2’s Blue Tablet.
FIRST CLEAR PRIORITY
Open the Gray Chest for the Green Tablet, then push west with N2
Carry the Gray Key to the Gray Chest and take the Green Tablet. Pair it with the Blue Tablet from N2 The Peaceful Village to open the West map into W1 Desert Ruins. On the same early pass you can snag the Blue Crayon Red Chest for Golf Building progress, then return later for the Red Skull Ring and Red Gem.

WEST GATE · GRAY CHEST
Green Tablet from The Vast Plain
Green Tablet
The Gray Key and Gray Chest both sit in the large early plain room family—rooms 0, 16, 17, 18, 19, 22, 25, and 26 depending on map state. Collecting this treasure is only half of the North → West event.
You also need the Blue Tablet from N2 The Peaceful Village Gray Chest. Holding both tablets opens the overworld route into W1 Desert Ruins.

Leave to the overworld
Exit the level so the North → West gate updates. Desert Ruins becomes reachable on the West map.
Push into W1
Clear scroll halves in Desert Ruins next if you are following the beginner treasure order toward Lead Overalls.
TOWER ROUTE · GREEN CHEST
Red Skull Ring and the Tower of Revival
Red Skull Ring
Find the Green Key in rooms 7, 10, 20, or 21, then open the Green Chest in room 9. The Red Skull Ring is one half of the pair that raises S3 Tower of Revival.
The other half is the Blue Skull Ring from W3 The Pool of Rain Red Chest. Collect both before you expect the Tower path beyond The Big Bridge to appear.

Para-Goom
Common early plain walker on open routes
Spearhead
Pointed hazard in mid-plain room sets
Mad Scienstein
Transformation pressure on side routes
Zombie
Night layout enemy on revisit sweeps

FAQ
The Vast Plain FAQ
How do I open The Vast Plain?
Finish the Gray Chest in N1 Out of the Woods for the Axe. The Axe cuts the overworld tree and unlocks N2 The Peaceful Village and N3 The Vast Plain together.
Where is the Green Tablet?
Gray Chest in The Vast Plain. The Gray Key and Gray Chest appear in rooms 0, 16, 17, 18, 19, 22, 25, and 26 depending on map state. Pair it with the Blue Tablet from N2 to open Desert Ruins.
What does the Red Skull Ring do?
The Green Chest holds the Red Skull Ring. Together with the Blue Skull Ring from W3 The Pool of Rain, it raises S3 Tower of Revival beyond The Big Bridge. One ring alone does not open the tower.
Where is the Blue Crayon?
Red Chest in rooms 11 / 23. It is one of the seven crayons used for Golf Building courses. See the Golf unlock guide for the full crayon list and door locations.
Why am I missing a Musical Coin in The Vast Plain?
On the default layout you can usually only collect seven Musical Coins. Coin 5 in rooms 7, 10, 20, and 21 appears after Magic Seeds open Variant 3. Set the finder to V3 and open the Musical Coins map.
Is Red Gem required for the ending?
No. The Blue Chest Red Gem is a collectible for the full 100-treasure Perfect screen. The main story ending needs the five Music Boxes; Perfect and Time Attack are post-story goals.
