Rocky the Jinx is a strange, crab-like creature with a shell that appears to be a rock. He is trained by the Gray Elves of the Sovereignty of Serenia to protect the Elven Caverns from the dangers of the Dark Forest of Serenia. When the Gray Elf was caught by Graham, he made Rocky move out of the way to reveal the only way out of the forest. It is unknown if Rocky is capable of speech or if Graham was able to understand him due to the effects of the white snakeskin he had ingested.
Rocky the Jinx is a character who appears briefly in King's Quest V: Absence Makes the Heart Go Yonder.
