The fastest and safest way to get the Crab Language Scroll is to unlock the Oxy Tube first, then dive west of Ancient Sands behind Grumpy Hank’s tower and retrieve it from the crab statue at the bottom.
Everything below explains why – and gives you a clear action plan.
What You Actually Need
You need:
- Oxy Tube from Lumi
- Around $57,000
- Access to Ancient Sands
- Enough Oxygen Pods for safety
Without the Oxy Tube, reaching the depth is inefficient and risky.
Tube Methods Ranked by Effectiveness
1. Oxy Tube (Best Method – Recommended)
Why it’s best
- Reaches required depth safely
- Minimal Oxygen Pod waste
- One clean dive
- Low risk
This method saves time and money long-term.
2. Boat Tube (Possible but Inefficient)
Why it’s weaker
- Heavy Oxygen Pod usage
- Multiple attempts likely
- High resource drain
- Slower overall
You may reach it, but it costs more in the long run.
Repeatable vs One-Time Requirements
One-Time Unlock
- Buying the Oxy Tube
- Finding the scroll location
Repeatable Resource Use
- Oxygen Pods
- General money farming for upgrades
Once you own the Oxy Tube, you never need to repurchase it.
Exact Location (No Confusion)
Go to:
Ancient Sands → West side → Behind Grumpy Hank’s tower
Then:
- Dive straight down.
- Reach the bottom.
- Find a large opening.
- Swim through the narrow tunnel.
- At the end, find a large crab statue.
- Take the scroll from its hand.
Simple. No side paths needed.
What To Do After Getting the Scroll
Go to:
Forgotten Deep → Henry’s Fish Shop
- Give the scroll to the crab near Henry.
- The crab becomes readable.
- You unlock a new quest.
- Progression continues.
Do not keep the scroll. It exists only to trigger the quest.
Fastest Action Plan (Step-by-Step Loop)
If you want zero wasted time, follow this loop:
- Progress normally until Ancient Sands unlocks.
- Move to Spirits Roots.
- Farm money using: Treasure chests, Suspicious Fisher quest
- Buy Oxy Tube from Lumi.
- Return to Ancient Sands.
- Dive west behind Grumpy Hank’s tower.
- Grab the scroll.
- Deliver to Henry’s shop.
- Start the crab quest.
Done.
No detours.
Common Doubts Answered

Technically yes with Boat Tube. Not recommended.

Final Verdict
Buy the Oxy Tube first.
It costs more upfront.
But saves time, oxygen, and frustration.
Follow the location path exactly once.
Turn it in immediately.
You will not need to search further.
