Twilly arranges ironic pranks - hijacking a garbage truck and dumping its load into Desi's convertible, and filling Stoat's Range Rover with dung beetles - but is aggravated when Stoat continues to litter. When he breaks into Stoat's home, he is confronted by his massive Labrador Retriever and by Desi herself. Desi, who is increasingly unhappy with her marriage, tells Twilly that he is "aiming low" if he is trying to correct Stoat's misbehavior. She guides him to Toad Island, where Clapley's construction crew has deliberately buried thousands of oak toads to avoid later protest by environmentalists. Twilly orders Desi to tell Stoat that he will kill the dog if he doesn't stop the bridge project. Stoat dismisses the threat until Twilly sends him a roadkill Labrador's severed ear via FedEx. The actual dog becomes Twilly's companion after he changes his name to "McGuinn."
