Maggot and Fungus have a week off school. Miss Justine has asked her students to work on an expose about their parents’ profession. Fungus really gets into it and decides to test “in the field” the new high productivity method he has just discovered in a book: he constantly bursts out singing “productivity, increased productivity and less coffee breaks!” for anyone who cares to listen… Rictus and Funerella are delighted and take advantage of this to go away for a week on a lovers’ holiday. But when Fungus wants to revolutionize everything in the hotel, the staff threatens to go on strike.
