The Toon Patrol
The Toon Patrol are a gang of toon weasels and the secondary villains in the film "Who Framed Roger Rabbit."
In the film, the Toon Patrol are the law enforcers of Toontown, although they behave more like vigilantes and mercenaries. Judge Doom has hired them to arrest Roger Rabbit for the murder of Marvin Acme. Their vehicle is a 'real' black 1937 Dodge Humpback panel truck which serves as a paddy wagon. The vehicle is fitted with official City of Los Angeles "Toon Patrol" decals on the front doors.
Like all the other Toons in the movie, the Toon Patrol are invincible to physical body harm except from a chemical blend called "The Dip." A combination of powerful solvents, The Dip dissolves the ink and paint which comprise the toons.
