Bling Bling, A.K.A. Experiment 504, is an illegal genetic experiment created by Jumba Jookiba. He is designed to turn things into fake gold to encourage excessive greed (does so by covers everything it touches in a layer of fake gold; the effects only last 24 hours but in that time the gold covered items will cause fighting and chaos as people try to own them).
Experiment 504 was the 504th genetic experiment created by Jumba with Hämsterviel's funding. He was designed to turn things into fake gold to encourage excessive greed.
504 and the other first 624 experiments were deactivated and smuggled to Earth by Jumba during his mission to capture Experiment 626.
All of the experiment pods were released and scattered across the island of Kauai.
At the unknown point, he was activated, captured, tamed and named Bling Bling.
504 was reprogrammed so that he could only cover metal objects in gold and that these objects wouldn't cause the excessive greed in those who see the items.
The effects only last 24 hours.
