Stone

Stone (ストーン, Sutōn) is a Copy Ability that debuts in Kirby's Adventure.

Kirby Gamble Galaxy Stories
Stone is an available Copy Ability in Kirby Gamble Galaxy Stories, but currently only in beta releases. It is toggled by pressing the 3 key on the keyboard. It allows Kirby to perform stone-based attacks, such as transforming into an immobile stone that is invulnerable to nearly everything. Stone is also able to break Star Blocks upon contact. Stone is primarily obtained from Rocky, and dons Kirby a hat composed of rocks and horns.

Moveset
Stone Kirby uses stone-based attacks, which involves Kirby becoming a stone or sculpture and smash objects and enemies from above of hitting them with other means.

Stone Sculpture Forms
Like in many games of the Kirby series, Stone lets Kirby take on various appearances with the sculptures, from a simple stone to statues referencing the series or HAL-related forms.
