Destiny can't cope with her new puppies, and a newly-single Vince takes Nelson for a night out. Marion is surgically castrated by Chico from the X-Factor.

Behind the scenes of the puppet-based adult comedy series Mongrels, featuring frank conversations and access to the cast, crew, puppeteers and celebrities.

A prototype version of Nelson (performed by Paul Kaye) pitches the show We Are Mongrels.

Nelson uses Toby Anstis's social networking login to set up a blind date with a human. However, he gets a shock when he discovers the Wendy he was planning to meet isn't a human being after all, but a chicken. Destiny joins owner Gary for the canine horror show that is Strictly Dog Dancing and falls for badboy Rivers from the dog disobedience class. If she is to see Rivers again, Destiny has to start behaving really badly. When Marion's owner dies, Kali sees an opportunity for Marion to pose as a missing cat called Chopsticks in order to rob his owner for all she's worth. Marion finds his new life most comfortable, until his new owner takes him to be neutered.

When his neighbor Vince has a litter of fox cubs Nelson is thrilled to be an uncle at last, until he finds that Vince has eaten all of his cubs except one - the runt of the litter. Nelson decides to save the runt, only to discover that he's the sickliest, saddest, most difficult animal you could ever wish to meet. Destiny meets a handsome dog called James who teaches her the art of the bottom sniff. Destiny quickly discovers that when it comes to sniffing bottoms she is an artist with special powers. Marion gets addicted to catnip and goes crazy. Nelson steps in with some aversion therapy in a bid to save his friend. Kali is reunited with an old partner in crime, the dove Dean. She is irritated to discover that Dean has no interest in helping her terrorise the neighbourhood since he has now found God and seen the error of his ways. Annoyed, Kali plots to tempt Dean back to the dark side.

Nelson discovers that the animals in Springwatch are actors, but auditions when he hears that Destiny loves the show. Marion falls for the beautiful but underage Lollipop. Destiny decides that guiding is for her and Kali reveals that she used to nest in Amy Winehouse's hair.

Destiny finds a knock-out strategy to win her dream man - John Terry's dog. Recruited by a secret society of bloodthirsty foxes, it's time for Nelson to kill or be killed. Marion is entranced by a peculiarly knowledgeable goldfish.

With Destiny on heat and trapped inside the pub by sex-crazed zombie dogs, Nelson has a once-in-a-lifetime chance to woo her. Marion's night in is ruined when Vince reveals he's a karaoke hog. And after a rickshaw driver runs over her dinner, Kali seeks explosive revenge.

Vince bumps into his old mate Danny Dyer. Kali struggles to win back her perch from a bolshy immigrant. Nelson falls for a feisty older vixen and runs into trouble with a disapproving relative. When Marion adopts Destiny's owner Gary, Destiny has to compete to regain his affection.
