🎯 Recommended Progression Path

  1. Wooden Tube (FREE) → Normal Tube ($350) - Skip Old Tube
  2. Pufferfish Tube ($2,850) - Skip Fire Tube, essential for Ancient Sands (120m+ depth)
  3. Rukiry Tube ($35,000) - Skip Boat & Zeppelin, better value
  4. Oxy/Plane Tube ($84,500 / $90,500) - Choose based on availability
  5. Ruined Tube ($270,000) - Best endgame tube, complete Lost Captain questline

💡 Oxygen Mechanics

  • Below 10% oxygen: Movement speed decreases
  • 0% oxygen: You "die" and lose inventory + money
  • Exceeding max depth: Oxygen depletes rapidly
  • Oxygen boosters: Sea Angel race (+25%), artifacts (Tank, Sea Star)

⚠️ Important Notes

  • Skip Fire Tube - Save $1,500, go straight to Pufferfish
  • Pufferfish is essential - Required for Ancient Sands (120m deep)
  • Weight matters - Higher capacity = more fish per trip
  • Speed is underrated - Ruined Tube's 32m/s is fastest

📍 Depth Requirements by Biome

Forgotten Deep: 0-100m - Normal/Pufferfish Tube

Ancient Sands: 120-300m - Pufferfish/Boat Tube minimum

Spirit Roots: 350-550m - Oxy/Plane Tube recommended

Angler Cave: 600-650m - Lost Spirit/Bath/Ruined Tube

🎯 Best Value Picks

1. Pufferfish Tube ($2,850) - Best early-mid game investment

2. Rukiry Tube ($35,000) - Skip expensive mid-tier tubes

3. Ruined Tube ($270,000) - Best stats, faster than Bath Tube
