Bobo has a day off and goes to Cronulla beach with his ex porn star girlfriend Ruby. The day explodes into mayhem as pizza deliveries go wrong and Habib and Rocky accidentally start a riot with lifesavers. The media then interview Pauly and he is taken out of context and blamed as the instigator of the Cronulla Beach riot.

Bobo does an insurance job on his old Fat Pizza pizzeria and buys a new shop in Hashfield Valley, because business is so bad he is forced to turn the shop into a pizzeria café carwash.

In response to a new Government ban on crackers and new "working for tips" laws the pizza shop workers suffer more grief than usual. Habib sets off all his old crackers before the ban is enforced, Davo is arrested for robbing a service station to pay for pizzas and Pauly drives to Canberra with Habib's cousin Omar to buy crackers.

Davo steals a police drug-sniffer dog and then tells the cops when the dog was suddenly cut up into pieces, then Chong Fat is suspected of the crime. Chong Fat admits that Davo had stolen the dog, Habib and Rocky had stolen the dog off Davo and offered him a ransom to pay if he wanted it back or else they would chop off its head. Davo is taken to the police station and tells the officers that Habib and Rocky then stole the dog off him. The cops arrested Rocky and Habib and took them to trial. Habib confesses that he took the dog but then gave him to Bobo who was believed to have cut it up to use for pizza meat. Bobo is then sentenced to trial and admits that Chong Fat had cut up the dog. Chong Fat is then taken into custody and sentenced to prison, Where he gets raped by a gay cellmate (the same inmate who also raped Habib in the earlier series of Pizza).

During an argument over cockroaches on Bobo's pizzas, Bobo accidentally bites off Rocky's finger. Both are sent to Hashfield Hospital, meanwhile Pauly is road raging all the hospital doctors and after bashing them there are no doctors to help Bobo and Rocky. In the end Junior decides to help with Bobo's surgery (after he lied to a Coconut Island nurse saying that he is a doctor).

Habib fakes the death of his wife, Toula, while she is in Greece whereby Habib receives $100,000. Bobo's gay Italian cousin Santino comes to visit from Italy. He shows Bobo how to make good pizzas. He gets a crush on DJ BJ. Bobo's mama goes interstate and Bobo has a barbeque to celebrate his engagement to his ex porn star girlfriend Ruby. Habib buries Toula's coffin (which he later tells Rocky there were only bricks in the coffin) and gets the insurance money.

Bobo holds a Melbourne cup lunch at Fat Pizza. Everything goes wrong, from bad food to power failures; the obese customers are unhappy at the lack of food and alcohol.

After causing the Cronulla riots and bashing radio shock jock Allen Ford Jones, Pauly and Junior are deported to Coconut Island, only there is a twist the department of immigration makes a mistake and they are sent to Crocodile Island.
