How to find it
The entrances are at map coordinates 3708, 608 and 3622, 583, near Lulu Lake. Look for the cave mouth at that spot; a Blupee or a ring of light often marks them.
Inside the cave
Enter Ploymus Mountain Cave and catch the Bubbulfrog
Ploymus Mountain Cave opens at the foot of the climb to Mipha’s Court at (3660, 538, 268). Walk in and light the cave with Luminous Stone. A Bubbulfrog glows among the coral on the lower ledge at about (3679, 523, 284); shoot it and take the first Bubbul Gem.


Open the chest for the Climber’s Bandanna
At the far end, past a ruined Zonai gate, a chest holds the Climber’s Bandanna, a headband that raises your climbing speed.


Climb through Pristine Sanctum
Pristine Sanctum has two entrances, at (3622, 583, 169) and (3708, 608, 343), reached by climbing the steps and waterfalls under the mountain. Inside, cross the flooded hall, climb the glowing pillar and take the second Bubbul Gem from the Bubbulfrog in the first chamber at about (3694, 639, 188).



Open the Arrow and Topaz chests
A chest on the path beyond the first chamber holds an Arrow; a little further on, a chest at the water’s edge holds a Topaz. Continue up the stairs to Mipha’s Court at (3838, 566, 491) to find Sidon.


Cave facts
| Entrances | Pristine Sanctum: the waterfall at Mikau Lake and a second way in from Lulu Lake (swim through the waterfall or drop in from above). Ploymus Mountain Cave: south-east of Pristine Sanctum and south of Lulu Lake, near a glowing cyan stone |
|---|---|
| Bubbul Gems | Two, one Bubbulfrog in each cave: in Pristine Sanctum on the cave wall to the left of the throne platform, in Ploymus Mountain Cave on the ceiling at the far end |
| Chests | Climber’s Bandanna (Ploymus Mountain Cave); a small chest with Arrow x5 beside where the frog falls in Pristine Sanctum; Topaz at the water’s edge |
| Requirements | Bow and arrows, Luminous Stone or Brightbloom Seeds for light; the climb uses little stamina |
In Pristine Sanctum, swim or climb up the waterfall inside, follow the stairs to the end, then jump off the middle platform and glide left to spot the frog on the wall. One or two arrows are enough, and the Bubbul Gem falls to the ground, so glide down and pick it up. The small chest of arrows sits right beside where it lands. In Ploymus Mountain Cave, light the dark cave, climb the rocks on the right to the platform and shoot the frog on the far ceiling. The sanctum also leads on towards Mipha’s Court. There are no Korok seeds inside.
