The Super Big Power Crystal is a jewel more powerful than its name is cumbersome and an object in Crash Boom Bang . It can grant one person their greatest wish by simply touching it before disappearing.
The search for this elusive stone was the Viscount's (as well as his grandfather's) life work. Crash Bandicoot wished for a vast amount of Wumpa Fruit and the wish was granted making the crystal disappear. The crystal was never mentioned or seen again in any Crash Bandicoot games since.
