Pui Pui Molcar is a Japanese stop-motion short series that premiered in early 2021, featuring adorable guinea pig-car hybrids known as 'Molcars.' Despite its target audience being children, the show became an overnight viral sensation on social media due to its charming animation, expressive characters like Potato, and surprisingly relatable adult themes such as traffic jams and social responsibility. In the meme world, Pui Pui Molcar is used for wholesome content, reaction images depicting wide-eyed shock, or ironic posts contrasting the characters' extreme cuteness with chaotic or dark situations. Its signature 'pui pui' squeak has become synonymous with internet sweetness and absurdist humor.
