Reception
Upon the series' release, it was received positively by both fans and critics in Japan. 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. The message is not explained in words, but is good from an educational point of view." She also added, "The current COVID-19 pandemic may actually influence the series' rise in its popularity."[28] Hakusai Kobayashi of Famitsu also praised the show for its animation and simple storyline saying "It has a high degree of perfection as an animation work. I'm guessing that's the reason the show has become popular." Kodansha's Japanese automotive magazine Best Car has featured the series in a three-page article.[29]
Reception outside Japan is just as positive. Kara Dennison of Otaku USA magazine stated, "Pui Pui Molcar doesn’t involve any dialogue (at least so far): just squeaks. And what makes it accessible for little kids also makes it accessible for international viewers."[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." Haddick added that the simple designs have caused the show to spawn fan art easily shared in social media and provide "a blank slate to personalize with self-made designs that fit into the basic idea of a Molcar. ... All the while, as plentiful YouTube videos show, it’s easy to make a Molcar of your own."[32]
The series also became a trending topic in Twitter in the month of January prior to its first airing.[33] Japanese media review company Filmarks ranked the series first place of the most popular anime in the 2021 winter anime season, beating other popular series like SK8 the Infinity, Non Non Biyori Nonstop and World Trigger.[34]
