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.
