Swashbuckle S05E17 - Coco-Nutty

Captain Captain has ordered Cook and Line to clean out the new shark tank, but they are scared of the sharks and decide to relax with a nice coconut instead. Captain Captain doesn't understand what there is to be scared of and she tells them that coconuts are actually more dangerous than sharks. You're more likely to be harmed by a falling coconut than a shark. This revelation backfires as Cook and Line now become terrified of coconuts, dressing up in elaborate coconut safety gear and trying to invent a coconut early-warning system!
