Ancient Shark (Stethacanthus)

Where

Sea-People ruins arena (stone-pillar room)

Weak spots

Underbelly (brown spots are armor and take zero damage)

Rewards

Harvestable meat for Bancho Grill.

Notes

Brown armor plating negates damage — the whole fight is about staying underneath and using pillar stuns to land the 200-damage mounted stabs.

Recommended setup

• Come in with as much ammo as possible — the fight starts right after fleeing the Sea People
• Stay below the shark so shots land on the unarmored underbelly

Attack patterns

• Lunge bite — narrow hitbox; swim above or below as it charges.
• Drill spin — coils and launches across the room; redirect it rather than just dodging.
• Chained drill spins (phase 2) — dodge the first, immediately prep for a second.
• Ceiling slam (phases) — retreats to the top and drops stalactites; keep moving (also knocks loose an O2 Pouch).

Strategy

1. Goad the shark into aiming its drill spin at a stone pillar — the collision stuns it.
2. Swim over while it's stunned and trigger the mounting mini-game (RT / equivalent).
3. Balance the Dave icon with the left stick; hold to the prompt, then stab for 200 damage.
4. Each pillar absorbs ~3 drill hits before breaking — track which are still usable.
5. After ~300 damage it does a ceiling slam (dodge stalactites, grab the O2 Pouch), then chains drills — repeat the pillar-stun-mount loop until it dies.
