Evolution Stone Tracker
Where to get Moon Stone in Pokemon Yellow
Yellow has five Moon Stones and zero Moon Stone shops. Grab the early ball on Mt. Moon 1F to evolve Nidorino into Nidoking, then sweep the remaining visible and hidden pickups with the checklist and map pins below.
Fast Answer
Mt. Moon first—never the department store
The first Moon Stone most players need is the visible ball on Mt. Moon 1F. Celadon Mart 4F sells Fire / Water / Thunder / Leaf Stones (₽2,100) but not Moon Stone. Two more visible balls sit on Route 2 (Cut) and Rocket Hideout B2F; two hidden stones hide on Mt. Moon B2F and Pokemon Mansion 1F.

Locations
All five Moon Stone pickups
- 1 Mt. Moon 1F
- 2 Mt. Moon B2F hidden
- 3 Route 2 (after Cut)
- 4 Rocket Hideout B2F
- 5 Mansion 1F hidden
Mt. Moon 1F · visible
Visible Poké Ball on Mt. Moon 1F. Grab it on your first pass through the cave after Pewter. If you already have Nidorino (Lv. 16 from Nidoran♂), evolve immediately for Nidoking’s mid-game coverage.
- Map target:
MtMoon1F - Kind: visible overworld ball
- Best use: first Nido evolution
Mt. Moon B2F · hidden
Second stone inside Mt. Moon on B2F. It does not sparkle as a ball—use Itemfinder (Route 11 aide, 30 owned) later, or search the hidden-item tile while you are already fossil hunting.
- Map target:
MtMoonB2F - Also here: Helix / Dome fossil choice
Route 2 · visible (Cut)
Visible ball on the east side of Route 2 (between Viridian and Pewter). Trees block the strip until you have HM01 Cut from the S.S. Anne captain and the Cascade Badge outdoor Cut rule. Open the map pin for exact placement next to the HP Up ball on the same ledge path.
Rocket Hideout B2F · visible
Inside the Game Corner Rocket Hideout on B2F. Collect it while chasing the Lift Key and Silph Scope—same dungeon chain as the key-items guide.
Pokemon Mansion 1F · hidden
Final spare Moon Stone on Pokemon Mansion 1F (Cinnabar). Bring Itemfinder while hunting the Secret Key on B1F. Useful if you saved stones for Clefable / Wigglytuff / Nidoqueen after the story Nidoking evolve.

Open the bag, select Moon Stone, choose the party mon. Evolution is permanent and the stone is consumed. Nidoran lines need the mid-stage first (level 16); stones do not work on unevolved Nidoran.

Play tips
Don’t waste your first stone
Nidoking first for most runs
The Mt. Moon 1F stone on Nidorino is the highest-impact early spend. Extra stones can wait for Clefable or a second Nido.
Level 16 before the stone
Moon Stone only works on Nidorino / Nidorina, not baby Nidoran. Train to 16 first.
Hidden stones need patience
Itemfinder from the Route 11 aide (30 species) makes B2F and Mansion trivial. Or open map markers and search the highlighted tiles.
Cut unlocks Route 2 freebies
Moon Stone + HP Up share the Cut strip. Sweep both when you return south after the Anne.
