Pan Ku Box
From Multiversal Omnipedia
The Pan Ku Box was a mystical artifact that features in The Jackie Chan Adventures cartoon.
Background
The Pan Ku Box was an ancient puzzle used by the eight Chinese immortals who used its magic to banish the Demon Sorcerors into the Demon Netherworld where they were trapped except for the dragon Demon Shendu. After his first defeat at the hands of Jackie Chan, Shendu decided to free his brethren from that limbo dimension and tasked the Dark Hand with using the Pan Ku Box to free his brothers and sisters.
The Box was a blue shaped puzzle that served as a guide to a portal into the Netherworld where a Demon Sorcerer was banished. Once solved, its centre would open revealing a greenish energy that would open the portal allowing the Demon to escape.
