 SCP-643 is a collection of 79 unmarked chocolate candies, with an abnormally low melting point. While refrigerated, SCP-643 possesses no anomalous effects or outward aesthetic differences from normal chocolates. SCP-643's anomalous properties will only manifest once the object is melted. Upon entering this state, SCP-643 will transfer itself onto any edible substance. Upon enveloping their host, SCP-643 instances will then begin to exude a strong, pleasant aroma. Subjects exposed to this scent report an irresistible desire to consume material coated in melted SCP-643.
