Momonga appears in Chiikawa, Nagano's manga series that began online in 2020 and later became a popular anime adaptation in 2022. The character is known for being demanding, spoiled and determined to be praised as cute, which makes even a simple moment like shaking off water feel like a performance. Clips of Momonga are widely shared by fans in short edits and reaction posts, where brief expressive sounds travel faster than full scenes. This shake has stayed in use because it sums up that playful attitude without needing dialogue or context.
