Object

The Wurrfler's Periscope

The submarine's periscope protrudes from the conning tower, its top three feet exposed above surging water. Indy scrambles onto the turret, lashes his bullwhip around it as a lifeline during submersion, and clings with legs locked while marine weeds tear at him. Sharks circle the tip at night; Nazis nearly spot his dangling whip at the dock as he hides inches from discovery.
