Mr Grumblebum gets a job at a lighthouse where he is given a list of jobs to be completed in a month. During this time he has quite a few accidents but gets most of the jobs done with help from Foo the Lighthouse Cat. Mr Grumblebum has a visit from an old friend, Shread the Dolphin. Late one night a boat sends out a distress signal and Mr Grumblebum sets off in the lighthouse boat to save the stranded fishermen.
