Kirby fans can now dive into some new and revealing facts about the pink puff.

Recently, the writers at Kotaku got to interview Shinya Kumazaki, chief creator at Kirby studio HAL Laboratory. One of their wildcard questions was on how Kirby’s feet (and by extension, his body) actually work.

While Shinya remained somewhat vague on the topic, he also divulged some interesting insight on how Kirby’s running animation came to be. Check it out below.

“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.”

“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!”

While we may never learn of how Kirby stores everything in his mouth, his child-like innocence makes a lot more sense now! We’ll report back when we have more interesting news of the pink puff to share.
