Ep. 7: Sam repairs the explosive mechanical fish to lure away alien creatures threatening the submarine.

7

Black Orchid introduces an alien fish species to the waters near Ocean Storm, drawn to the steel alloy of the submarine's hull. In response, the Automated Construction Plant fabricates a mechanical decoy from the same material, embedding it with an explosive charge and naming it Ocean Diner. This device successfully lures the alien fish away from the vessel. However, the explosive fails to detonate as intended. Sam is forced to swim toward the mechanical fish to manually repair the charge while under attack by the hostile alien creatures. Despite the danger, he completes the repair, causing the decoy to explode and destroy the alien fish, thereby neutralizing the threat to the submarine.
