Mochi Mochi Ducks are creatures that exist somewhere between the Japanese rice cake "mochi" and ducks. They were created by moca, a Japanese artist and character illustrator. These adorable ducks melt, bounce, and stretch just like mochi. They are free creatures who live however they like, in any shape they want, eating whatever they please. They're a lovable character that helps make our sometimes stiff days a little softer.
