The Catseye of Doom was a legendary jewel which had been sought after by treasure seekers for centuries. It was known to be located on Planet Doom, because the jewel had originally been part of a statue of the Cat Goddess of Doom. However, the Caves of Doom in which both the statue and the lost jewel were hidden, were so filled with traps and Ghosts, that it was nearly impossible to complete the quest for the Catseye.
