Rocky has two different appearances depending on the game he's in. In Kirby's Adventure, Kirby Super Star, and Kirby Super Star Ultra, Rocky is a orange stone with the headband Hammer Kirby uses. In Kirby's Dream Land 2, 3, and Kirby 64: The Crystal Shards, Rocky has a larger, more hexagonal shape and an overall more aggressive appearance about him.
Rocky just sits there, occasionally walking very slowly, usually off a cliff or edge to drop down and crush whatever is beneath him.
