Diving Bell Spiders leave sealed web pockets under the water in Grounded 2: Into the Abyss. Those Diving Bell Sacs hold insect parts, but they stay closed until you bring a stronger Omni-Clipper and enough air to reach them.
Quick answer: Buy the Omni-Clipper level 2 upgrade at a Ranger Station, wear a Gill Tube, then clip the bubble-leaking web sacs along Skunk Pond and The Bridge.

Diving Bell Sac drops
A clipped sac spills its contents on the spot. That burst is the check that the tool rank is high enough. You should see a pile of insect parts, not an empty husk.
| Drop | How often |
|---|---|
| Tadpole Meat | Common |
| Water Boatman Fin | Common |
| Other insect parts | Common |
| Tier 2 materials | Regular |
| Tier 3 materials | Uncommon |
The spiders themselves are a separate pickup. A dead Diving Bell Spider can drop a Diving Bell Spider Chunk and web fiber. Those chunks feed new pond armor and gear, so leave pack space for both the sac loot and the corpse loot.

A stock Omni-Clipper will not open a Diving Bell Sac. Rank 2 is the lock. The upgrade also needs one Diving Bell Spider Chunk, so kill a spider before you visit the station if you do not already have a chunk.
| Upgrade cost | Amount |
|---|---|
| Science Points | 2000 |
| Diving Bell Spider Chunk | 1 |
| Crow Feather Pieces | 2 |
Gill Tube and Fin Flops
The sacs sit underwater. You need a Gill Tube so the dive lasts long enough to clip them. Fin Flops help you cover the pond banks before the air runs out. Craft both on the surface first.
| Item | Materials |
|---|---|
| Gill Tube | Wax, Eelgrass Strand, Silk |
| Fin Flops | Water Boatman Fin, Eelgrass Strand, Wax |
Wax sits on Water Lilies. Eelgrass Strand comes from algae near the pond shore. Cut that algae with the Omni-Clipper, and stay shallow so you can surface. Water Boatman Fins drop from Water Boatmans around The Bridge.
Diving Bell Sac locations
Search the banks of Skunk Pond and The Bridge. The sacs are web-like structures under the surface. Many of them leak a stream of small air bubbles, which makes them easier to spot in murky water.

Those bubbles do not refill your oxygen. Treat them as a marker only. If you linger on a sac waiting for a breath, the gauge will still empty.
Opening Diving Bell Sacs
Diving Bell Spiders hunt anything that moves in that water, including you. Clear the owners before you stand on a sac. A Harpoon Gun and Bolts make that fight much shorter.


If nothing comes out, the clipper is still below level 2. Surface, return to a Ranger Station, and confirm the upgrade before you dive again. Grab the spider chunks on the way up so the next armor craft is not a second trip.
