The van has a two-tone green and white color scheme with two doors in the side, one of which has a broken lock and a window roller. It has four rows of seating; one with the drivers' seat and adjacent passenger seat and three with seats for other passengers. The license plate reads "LLLD", as seen on "A Tattler's Tale" (however, A Flipmas Carol shows it having a license plate reading "3MTA3"). On the front of the van is the word "FUNG", which may be the name of the van's manufacturer. Likewise, the rear door has a badge with the initials "FMC" on the lower right, which may stand for "Fung Motor Company".
Despite the van bearing no distinct resemblance to any other real life vehicle, it takes design cues from various vans of the 1960s. The front grille resembles that of a 1964-1970 Dodge A-100, and the headlights slightly resemble those of a 1962-1967 Ford Falcon Club Wagon. The rear profile of the van also appears to be taken from the Econoline. It also has the split-screen windshield and taillight placement of the 1950-1967 Volkswagen Type 2. However, it also has some traits of more modern minivans, giving the van a more anachronistic appearance. The windows on the van are much larger, less round, and has less windows than 1960s vans. It also has single rear doors on both sides that are hinged, similar to the 1994-1998 Honda Odyssey.
The name of the van is most likely a pun of the famous Japanese monster Godzilla.
The presence of the name Fung may be a reference to either the Chinese-American cartoonist Paul Fung (1897-1944) (who authored Chic Young's Dumb Dora comic strips from 1930 to 1932 after Young created Blondie, and assisted Billy DeBeck in Barney Google and Cliff Sterrett in Polly and Her Pals) or his son Paul Jr. (1923-2016) (who also assisted Young in Blondie from 1949 to 1965).
Despite getting destroyed by the kids' violent brawl in "The Sweet Spot", it is seen perfectly intact in subsequent episodes.
It is possible that the van was rebuilt after the events of that episode.
A similar-looking van appears in "The Whole Picture", when Lincoln and Clyde are looking at the former's recreated childhood photos.
"Tripped!" reveals that Lily can say its name, but she pronounces it "ban-zilly".
"The Sweet Spot" reveals several things about its seating arrangement:
If a kid sits in the front row, they are more likely to be told off due to being nearest the parents. Conversely, if a kid sits in the back row, they are less likely to be told off due to being farthest away from the parents.
The last seat in the middle row tends to slant forward.
One of the seats in the middle row has a faulty spring.
Lisa enjoys sitting in the back row, because she feels it is safer.
"House of Lies" reveals that the van used to have orange carpeting.
