The series is aired as a two-minute-plus short animation segment on the children's variety program Kinder TV.

These unnamed Molcars are being retroactively given names and monikers through a series of Twitter posts as part of a countdown to the compilation movie's release.

The show also depicts human and non-human characters, mostly depicted as faceless figurines, although in several episodes, interior shots are shown as limited live-action scenes where drivers and passengers are played by actors; the first episode alone sees portrayals by director Tomoki Misato and older sister Mizuho, herself an actress.

Tomoki Misato is a stop motion animator and director born in Tokyo, Japan and graduated from Musashino Art University in 2016.

[6] As an upcoming director, he began working with Pui Pui Molcar after being approached by Noboru Sugiyama, the executive producer at Shin-Ei Animation in an offer with Bandai Namco Entertainment to produce a short animation series that would air as one of the segments in Kinder TV.

Almost all of the episodes of the series was directed and written by Misato himself, though he was assisted by an animation crew composed of four people at Japan Green Hearts alongside Hana Ono and many others.

A second season aired on TV Tokyo from October 8 to December 24, 2022, with Hana Ono directing the series and UchuPeople taking over as main animation studio from Japan Green Hearts.

Muse Communication licensed the series outside Japan to be aired also in YouTube in South and Southeast Asian territories.

[13] Netflix is streaming the series in North America and other select territories excluding some parts of Asia starting March 25, 2021.

At one point, the Molcars' shenanigans cause Potato's driver to briefly awaken, only for her to go back to sleep upon seeing nothing superficially unusual.

The film is directed by Mankyū, with Tomoki Misato credited with chief supervision, and Yuuko Kakihara writing the script.

[19] On August 5, 2024, it was revealed that the movie's release would be on November 29, 2024, and that it would include voice acting from Arashi's Masaki Aiba, and Akio Otsuka, who will play human characters in the Molcar's world.

The show has also announced a collaboration with Bandai Namco Filmworks to promote the release of Mobile Suit Gundam: The Witch from Mercury, accompanied with an artwork by JNTHED.

Naoki Ogi, an educational critic, stated, "Reading the story from music, movements, and facial expressions in an anime without dialogue stimulates the imagination of children.

"[30] Leandre Grecia of Top Gear Philippines found Pui Pui Molcar enjoyable even for older viewers, saying it is "a feel-good no-dialogue series containing sub-three-minute episodes, and we dare say the entire show has a decent mix of comedy, drama, and action."

Grecia also added that the show teaches children "some subtle lessons on social responsibility, which can help give kids an idea or two on how to act properly toward other people and animals, and the environment.

"[31] Alicia Haddick of Otaquest mentioned that among the reasons for the series' popularity in and out of Japan are the simplistic design and inviting setting along with the Molcar concept, commenting that "Turning [cars] into the equivalent of pets and having them act as such is also an ingenious move that only endears them to the audience."
