Howard and Vince travel to the arctic seeking the Egg of Mantumbi.

Howard is going to fight a kangaroo but he needs some training first.

The animals are disappearing from the zoo and it's up to Howard to find them.

Bollo is deadly ill and when the grim reaper comes to take him to hell, Howard is in Bollo's cage in a gorilla suit. So the grim reaper takes him instead.

Not wanting to live in the shadow of the charming adventurer Dixon Bainbridge, Howard convinces Vince to seek the Egg of Mantumbi in the dangerous tundra - the home of the demon Black Frost.

With the zoo sale and destruction imminent for a future road, Howard's only chance to save the zoo is to find his previous boss: Absentee owner, and hero Tommy Nookah who is hidden within the bizarrely large 'Jungle' section of the zoo.

Howard is hell-bent on a career as a serious writer in the hope that he will improve his chances with Mrs Gideon. However, when famous publisher Hamilton Cork arrives at the Zoo-niverse, he decides to publish Vince's literary efforts about a pink bubblegum character called Charlie. Meanwhile, Bob Fossil has embarked on a new breeding programme for the pandas.

Vince is convinced that The Human League invented music. According to Vince, Howard's past career as a jazz trumpeter does not measure up. When Vince is offered a chance to join a new band, 'Kraftwork Orange' with Johnny Two Hats and the Electro Girls, he's intent on leaving everything behind, including Howard.

Bob Fossil has a big problem at Zoo-niverse. Ivan the bear has developed some very anti-social habits and attacks Fossil. After Naboo saves his life, Fossil arranges a place for Ivan at an Animal Offenders' Institute. All he has to do is find a couple of idiots to drive Ivan there in the clapped-out old Zoo-niverse van. All Howard and Vince have to do is get there and back, in one piece, without falling foul of the Hitcher.
