How to find it
The entrance is at map coordinates 4243, -255, near Horon Lagoon. Look for the cave mouth at that spot; a Blupee or a ring of light often marks them.
Inside the cave
Dive into the lagoon
The entrance lies under the surface of the lagoon, beside the rocks at its edge. Dive in and swim down into the cave mouth; Brightbloom Seeds help you see.


Catch the Bubbulfrog
Surface in the inner pool and watch for the glowing Bubbulfrog. Hit it and take the Bubbul Gem from the water.


Open the Rubber Tights chest
Swim on to the carved gate with red banners at the end of the cave. The chest inside holds the Rubber Tights.


Route, enemies and tips
- Entrance: one, at the north end of Horon Lagoon, 4243, -255. It is a chasm or hole in the ground; the easiest approach is to glide in from above.
- Flooding: the water level keeps rising and falling. Heading southeast you must wait for the water to rise so you can swim over the spikes.
- Enemies: a Black Horriblin near the entrance can be knocked into the water to drown it. Bomb Flowers are plentiful.
- Bubbulfrog: in the large open, water-filled room. Hit it for the Bubbul Gem.
- Chest: at the far end, breakable boulders sit up on the wall behind a rubble wall. Attach a Bomb Flower to an arrow and shoot it to blow the wall open; the chest inside holds the Rubber Tights, the last piece of the Rubber Armor set.
- Korok seeds, shrine: none inside; the nearest shrine is Apogek Shrine. Materials include Diamond and Topaz deposits and Brightbloom Seeds.
