Stone

Stone is an ability of Kirby's in the Kirby and Super Smash Bros. series. It originated in the NES title Kirby's Adventure, where it was a copy ability of the pink puffball's. When executed, Kirby will turn into a stone and drop onto an enemy, thus damaging it. This would work the same way in the Super Smash Bros. series, though to perform it the player controlling Kirby would have to press down B.

In the original Super Smash Bros., Kirby would just turn into a stone, though in Super Smash Bros. Melee Kirby would be capable of turning into a stone, a Thwomp, a garbage block from Panel de Pon, a 100 ton weight, and a spiked ball.
