The Dip Sprayer is a vehicle with a large vat filled with Dip. It was built and invented by Judge Doom. He plans to spray throughout the area, wiping out all the Toons. Valiant manages to open the drain on the Dip sprayer, showering Doom with the mixture and dissolving him and drained all the dip from the machine.
The emptied Dip sprayer harmlessly crashes through the warehouse wall into Toontown, but failed to destroy Toontown and immediately smashed by a Toon train.
Who Framed Roger Rabbit
Judge Doom, a toon disguised as a human, used this machine in an attempt to kill Roger Rabbit and Jessica. Eddie managed to use the Dip on the lead weasel by kicking him into it. Then Eddie opened the machine's drain, releasing a torrent of Dip at Doom, melting him down to paint.
The emptied Dipmobile then crashes through a wall and was crushed by an oncoming toon bullet train, being destroyed by the very vehicle it was intended to replace.
The Dip Sprayer 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 Backlot Tour.
