Out searching for her in a boat guilty Fry knowing how futile this action is drinks the potion and dives in after her (changing into Californian Linefish in the process) leaving the Professor and Chuck on-board as an storm brews overhead.

Now these three find themselves stranded in the ocean in a desperate search to find that antidote. However on the seabed their antidote has fallen into the fins of the ruthless pilot-fish Joe...whose exposure to it has increased his intellect, making him power-mad with no intention of letting this stroke of fortune desert him.
