A sudden hurricane tears through the sanctuary and separates Bob from Julia, forcing him to navigate the wreckage alone and save several animals in need. Bob then crosses the flooded city to the animal shelter, where he discovers his long-lost sister Boss caged inside, and Ivan and Ruby arrive to help rescue all the trapped animals from the rising water. Bob pushes further into the storm to save Boss's sickly puppy Rowdy, rescuing him from the floodwater and then from the jaws of the wolf Kimu in the novel's climax.

In his current domesticated life with Julia, Bob is mocked by Nutwit and the hamsters for being as pampered as Snickers, and he witnesses the heartbreaking submission of a neglected neighborhood dog named Droolius, which deepens his complicated feelings about human ownership. A nightmare about his friends drowning foreshadows the coming disaster, and Bob's unease at the sight of the wolf Kimu in his enclosure plants a seed of dread. When the hurricane strikes, Bob must confront his fear of Kimu directly as the wolf roams free through the damaged park, and Bob cowers before him for the first time up close. Inside the flooded shelter, Bob takes charge by directing terrified animals to safety and memorizing instructions for Boss, before Ivan and Ruby's dramatic arrival turns the tide — and the aftermath leaves Bob devastated when Boss slips away before he can bring her home.

His identity crisis sharpens during a visit to Ivan and Ruby, where Ruby's playful riddles and Ivan's quiet concern reveal how carefully Bob hides his vulnerability behind humor and bravado. The hurricane forces Bob to make a series of decisive choices — fleeing the park against orders, crossing the flooded city alone, and ultimately confronting the guilt he has carried since abandoning Boss on the highway as a puppy. Boss's forgiveness and her unexpected advice to release their anger toward their first owners shocks Bob and begins to crack open his emotional armor, while a surprising confession from Snickers during the rising floodwater signals that Bob's defenses are finally softening.
