Matthew Handy, who is worried over the excessive use of cars by the citizens of Tipsville, decides to propose Mayor Cleanhands an interesting alternative: the creation of a bicycle service from City Hall that favors a transportation method that does not pollute the city. Darkhand, alarmed over the possible decrease of the use of putrillio, decides to support the creation of a gang of thugs, lead by Hand Slap, that will ride bicycles causing chaos to the citizens by acts of vandalism. Taking advantage of Mayor Cleanhands visit to the school, Matthew's kids, Anna and Paul, are able to convince the mayor of the importance of bikes as an urban transportation method, and at the same time, they will hand over information needed to capture Hand Slap and his henchmen.
