To get Sunken Bone in Grounded 2’s Into the Abyss update, dive in Skunk Pond near Gnarly Bark and the Pirate Ship, then dig the muddy bone nodes with a Tier 3 shovel while wearing strong swim gear.
Sunken Bone comes from buried underwater nodes in Skunk Pond after Grounded 2’s Into the Abyss update, which went live on August 11. Go in with oxygen gear, Fin Flops, and a Tier 3 shovel, drop near the Pirate Ship, dig the cluster fast, then surface before the cold water and oxygen drain catch up. Here’s the exact route.
What you’ll need before the dive
| Need | Details |
|---|---|
| Oxygen head gear | Koi Scale Helmet for the longer oxygen timer; a breathing tube also works |
| Swim gear | Fin Flops for faster swimming and a quicker dive |
| Shovel | Tier 3 shovel, such as the Black Ant Shovel, to dig the buried bone nodes |
| Skunk Pond hazard | Cold water applies a Chilling effect and oxygen drops fast |
Farming Sunken Bone keeps you underwater long enough for your gear to matter. The key piece is head gear that extends your oxygen — the Koi Scale Helmet is the best pick here, though a basic breathing tube gets the job done if that’s what you have. Pair it with Fin Flops for faster swimming and a quicker drop to the floor, and bring a Tier 3 shovel, because the bones are buried nodes you dig up rather than loose pickups.
Skunk Pond water adds pressure the entire time. It applies a Chilling effect, and your oxygen meter drains while you’re under, so run the route cleanly: dive, dig the cluster, and surface before the cold and the empty air bar force you out.
Where Sunken Bone shows up in Skunk Pond
The route starts in Skunk Pond, right next to the Gnarly Bark landmark. Once you’re in the water, head for the pond floor around the Pirate Ship, the sunken wreck that pops as a landmark discovery when you reach the right depth.
If you played the first Grounded, skip the old Koi Pond depths route. The Into the Abyss update rebuilt the underwater areas, and this Skunk Pond cluster is a Grounded 2 location, not a carryover from the original game. Use Gnarly Bark and the Pirate Ship as your anchors.
How to reach the Sunken Bone cluster in Grounded 2
Key This dive drops you onto a tight cluster of buried Sunken Bones near the Pirate Ship, so line up your gear and go in ready to dig fast.
STEP 1/7
Set your dive at Skunk Pond
Open the map, find Skunk Pond right next to Gnarly Bark, and swim out to the dive point.
STEP 2/7
Drop straight down, fast
Dive into the water directly in front of you and swim straight for the pond floor as quickly as you can.
STEP 3/7
Reach the first bone cluster
Three Sunken Bones sit close together here — one is right in front of you, with another tucked just behind it.
STEP 4/7
Dig each node with a Tier 3 shovel
A Tier 3 shovel like the Black Ant Shovel is required to break the muddy node loose and loot the Sunken Bone.
STEP 5/7
Sweep to the right
After clearing the front pair, move to the right side and dig the next Sunken Bone waiting there.
STEP 6/7
Turn around for the one behind
Look directly behind you, near the Pirate Ship landmark, to find another Sunken Bone in the mud.
STEP 7/7
Check beside the Koi Scale on the left
To the left, next to a patch of Koi Scale, sits one more buried node — dig it, then pull out fast, since a creature nearby can reach you.
Clear every buried node in the cluster in a single dive before you surface — with a Koi Scale Helmet on you have enough oxygen to grab the whole group, and backtracking just costs you a second cold-water trip.

Other finds and dangers along the route
The same patch of pond floor gives you more than bones. You’ll see Koi Scale scattered under you near the last dig spot, and the buried nodes on that left side can come up as either a Sunken Bone or a Koi Fish Scale, so dig them all and sort the loot afterward. The Pirate Ship registers as a landmark discovery on your way through, and clearing the area can trigger the Merteen mutation notification.
Watch the water around you while you dig. Water Fleas patrol around the deeper bones, and a creature down there can reach you mid-dig, so grab the nodes and swim out instead of trying to fight on a draining oxygen bar.
What Sunken Bone is used for
In the first Grounded, Sunken Bone was the backbone of the underwater kit — it fed the Bone Dagger, the Bone Trident, and the Bubble Helmet that doubled your dive time. Those recipes are why players farmed it in bulk.
In Grounded 2, stockpile Sunken Bone and check your workbench after the Into the Abyss update for the recipes it opens up. The update leans hard into diving, so a strong underwater material like Sunken Bone is worth gathering before you need it.

Frequently Asked Questions
Can you use an Acorn Shovel for Sunken Bone in Grounded 2?
Use a Tier 3 shovel for the buried nodes in the Into the Abyss Skunk Pond route. The Acorn Shovel handled digging in the first Grounded, but this route calls for a Tier 3 shovel so you can break the nodes and loot the Sunken Bones.
Is the old Grounded Pond Sunken Bone route the same in Grounded 2?
No. The 0.5 update rebuilt underwater movement and combat and reworked the pond areas, so the first game’s Koi Pond depths route doesn’t map onto Grounded 2. The spot now is Skunk Pond near Gnarly Bark, with the bones clustered around the Pirate Ship.
Does Sunken Bone respawn in the Into the Abyss update?
Respawn timing varies, so treat the Skunk Pond cluster as a repeat-farm route. The 0.5 update switches on resource regrowth, but the same nodes will not be back the moment you resurface.
