Creeping Coin

A type of mimic which has a shapeshifting ability. They masquerade as mountains of coins, sacks stuffed full of them, etc., and lie in wait for human male prey. They basically appear in places visited by adventurers and tomb raiders such as old castles, towers, and the like, but there are reports of them rarely managing to sneak even into places such as national treasuries. They reveal their true forms when men who fall for the trap touch or approach their disguised body.
