Dip Machine

The Dip Machine (a.k.a. The Dipmobile) is a vehicle in Who Framed Roger Rabbit. It is a large vat built and invented by Judge Doom to spray gallons of Dip, wiping out all Toons, and melt Toontown into oblivion.

Who Framed Roger Rabbit
The Dip Machine is seen during the climax of the film. Greasy can be seen working the controls in the cab of the Dipmobile. Judge Doom attempted to kill Roger and Jessica Rabbit with the Dip machine's spray cannon. During a scuffle with the Toon Patrol, Eddie Valiant managed to kick Smarty into its vat, instantly killing him. In the climactic battle with Doom, Eddie managed to open the Dipmobile's valve with a boxing glove, releasing a torrent of Dip on Doom, melting him. The Dipmobile then crashed through the warehouse wall into Toontown and was immediately rammed by an oncoming toon bullet train, never to be seen again.

Disney Parks
The Dip Machine appears in Roger Rabbit's Car Toon Spin towards the end. The original prop vehicle is located at Disney's Hollywood Studios, having been displayed in the boneyard of the Studio Backlot Tour.
