Guysborough is the Big Harbour's garbage barge who has a grumpy personality and calls everyone else "rotten". He is disagreeable in both aroma and temperament.
The only ones who can stand him are Jasper, Theodore and Digby. His catchphrase is "Theee-o-dorrre!" ... which Theodore once used as a foghorn when the lighthouse was out to prevent a shipwreck, in a hilarious solution to an otherwise serious problem. He enjoys the stench and dirty work of collecting garbage and absolutely hates being clean.
