The fly-on-the-cage-wall documentary returns, with more stories about the animals of Chester Zoo. The keepers suspect Margery the Malayan tapier may be eating for two, while James Bond the macaw is put into quarantine to ensure he does not have the same disease that killed his partner, Miss Moneypenny. The tiny but mighty golden mantella frog family is in need of a breeding boost, with hopes resting on minuscule male Eddie, who needs to summon up all his stamina to successfully court his frog princess Fergie.

Chester Zoo's alpha male lion is having a crisis of confidence. There's been a bloodbath among the vampire crabs. And affable Andean bear Bernie has been kicked out of the family paddock.
