Zip Turbine captains the finest mostly-legal cargo hauler in the galaxy, Nana's Hog. The problem is, her latest parcel won't shut up. Pilsen is a political outcast turned reluctant ambassador to a planet filled with giant, psychic crabs.
Negotiations last all of twenty minutes before Pilsen is kidnapped by an armed lobster militia. Forced into the role of bodyguard, Zip has to join up with an anxious five-foot-tall talking shrimp, Tom. Together, they venture deep beneath Crustacea's ocean to rescue the ambassador and make sure Zip doesn't lose her paycheck.
