- “Your little slip up will be a minor bump in the road so long as we've got the prince's blood in this.”
- ―Facilier to Lawrence
Given to the voodoo doctor by his "friends on the other side", the amulet is capable of transformation spells in two manners: it can pinch someone with its mouth-like compartment, inflicting a transformation spell onto the victim while at the same time, being able to take a sample of their blood. After taking in a blood sample, the talisman allows its wearer (except Facilier) to take on the appearance of the blood donor. However, in order for this transformation to last, the talisman must be constantly refilled with the victim's blood, otherwise, it will run out and the wearer will slowly revert to his original appearance as the last of the blood is drained out.
For Facilier's plot to steal the La Bouff family fortune, Lawrence wore the talisman to disguise himself as Prince Naveen in order to marry Charlotte La Bouff. However, once this is discovered by the real Naveen and his friend Ray the firefly, the duo are able to steal the talisman and hand it over to Tiana. Once in Tiana's possessions, the talisman is destroyed (much to Facilier's horror), thus saving Charlotte's fortune and New Orleans. Being the most vital part of Facilier's plot, the talisman's destruction also resulted in the witch doctor's death.
- Ray referred to the talisman as a "voodoo hayacall". A "hayacall" is merely Cajun slang term used for objects for which the name is unknown.
