It made to look like a Krabby Patty with pickles for wheels two lights on the front of the car.
The SpongeBob SquarePants Movie
The Patty Wagon first appears in The SpongeBob SquarePants Movie, where SpongeBob and Patrick ride it to Shell City. It is stolen as they cross the county line. However, it is then brought to the Thug Tug (a rough biker bar), in which SpongeBob and Patrick are able to get it back. They then ride it through the abyss. After they land on the road after a jump while dodging the fake ice-cream vendor, they are separated from the Patty Wagon, which is then eaten by a frogfish and then by a larger fish. It is presumed to be lost and destroyed.
SpongeBob is seen in the patty wagon thoughtout the game driving it.
The SpongeBob SquarePants Movie video game
Outside of the movie, the vehicle appears in The SpongeBob SquarePants Movie video game in the driving levels "Sandwich Driving 101," "No Weenie Parking Anytime," "Sundae Driving," and "Drive of the Knucklehead-McSpazitron." Despite having been eaten by the frogfish earlier in the game, Mindy is able to retrieve it for SpongeBob and Patrick prior to the start of the "Drive of the Knucklehead-McSpazitron" level if the former gives her fifty Goofy Goober tokens. If the player causes damage to the Patty Wagon too many times, it will break down by its ingredients dissolving, thus restarting the level.
The SpongeBob Movie Game: Sponge on the Run
It can be used during a run to destroy obstacles. It costs 1 bottle to use at the start of a run if desired.
SpongeBob is seen in it trying to get away for Plankton who is chasing him.
Nick Racers Revolution 3D
It was one of the vehicles for SpongeBob and Patrick.
Almost every part of the car is designed to be food or food-related. The car has:
Sesame seed surface finish
Grilled leather interior
Radial pickles (also called "Steel-belted")
Fuel-injected deep fryer with dual overhead grease traps
Fork-shaped gas pedal
Spatula-shaped ignition key
Krusty Krab-sponsored flag
Vehicle registration plate that reads, "2-GO."
Glove compartment (owner's manual for Patty Wagon found inside)
Both Patrick and SpongeBob know how to drive the Patty Wagon.
According to SpongeBob, he doesn't need a license to drive it.
The ingredients on the Patty Wagon are not connected to each other (seen when SpongeBob and Patrick bashed the wall of the Krusty Krab 2 and the ingredients/parts fall down to each other). It is unknown how the Patty Wagon works.
It was revealed that the patty wagon has a manual transmission. SpongeBob is seen making an "S" like shifting maneuver, seemingly shifting from reverse to first. Also, while SpongeBob's driving away from the Thug Tug, a 3rd pedal can be seen, most likely a clutch. Both these features are exclusive to manuals.
Also, the fact that it runs on fry oil probably means it's a diesel engine set-up. Likewise, diesel fuel isn't volatile enough to burn in a spark-ignition gasoline engine.
This is a particularly interesting joke on SpongeBob's driving skills; as he is able to drive a vehicle (that's not a boat) with a manual transmission (which takes significantly more coordination to drive) on city and country roads, while failing miserably driving an (presumably) automatic on a closed course.
It is likely all Krusty Krab employees know the shift pattern by heart (there is roughly a dozen types of shift patterns on manual transmissions) as SpongeBob was able to (presumably) shift effortlessly, despite there being a customized shift knob. Patrick probably watched SpongeBob shift (enough to know where reverse and first gear are), as he was seen backing up and driving forward to save SpongeBob.
It is likely for it to have rear wheel drive judging by the burnouts and peelouts.
Its name is a pun on "Paddy Wagon."
Despite not appearing in the second movie, the Patty Wagon is a usable vehicle in The SpongeBob Movie Game: Sponge on the Run.
Northern Leisure Group made the ride out of the Patty Wagon featuring SpongeBob and Gary. The ride features sing-a-long lyrics in time with the theme tune and horn, bubble and dolphin sound effect buttons.
SpongeBob is seen driving this vehicle throughout the online game Delivery Dilemma.
