Geezi is a snitch, and he has one of the Queen's memory birds (so she doesn't
use disks for data storage and retrieval, okay?). The Rangers go back to
Tortuna (this time undercover as Zanguils) to buy the bird from Geezi, and
they learn about how the Queen has decimated the Gherkin race along the way.
Doc almost gets turned into a slaver lord, but you gotta watch it to see how
everyone gets away.
