The Sea (open ocean surface around the Wurrfler submarine)

Moonlit, cold, churning open sea surrounding the Wurrfler submarine's conning tower. Waves lap and sometimes flood the deck as Indiana Jones bursts from the depths, soaked and hatless, clawing up the slick surface and tying his bullwhip to the exposed periscope while dark shark fins cut the water and form a tightening ring. The vast expanse becomes a claustrophobic, predatory barrier that isolates the vessel and tests Indy’s survival against relentless force.
