Kotaku has announced that they have done a few interviews with HAL Laboratory via email. Multiple people took part in the interviews, including Shinya Kumazaki, HAL Laboratory chief creator. One of the questions that Kumazaki received was what Kirby‘s feet look like. Kumazaki’s email reply was that “it’s definitely a unique question. I couldn’t help laughing a bit. But I’m afraid the mysterious composition of Kirby’s body is top-secret”.
However, Kumazaki wasn’t finished answering the question. Kumazaki continued, saying that “I would like to talk a little bit about designing the running animation where Kirby’s feet kick out into the air while running across the ground. Kirby’s body is uniquely shaped compared to us humans, but the animation we designed is reminiscent of movement that’s not so different from humans walking. It was created based on the idea of a human running energetically, with the thighs, knees, and ankles invisible, but nevertheless accounted for. That concept has been used in drawing the movement of Kirby’s hands and feet ever since Kirby was made up of pixels. So maybe rather than getting hung up on Kirby’s soft round body, picture a lively child running around a wide meadow, then take another look at how Kirby’s feet move”.
