((You heard about a dungeon with lots and lots of gold and coins, but it's inhabited by creeping coins. Creeping coins are a type of mimic that disguises itself as piles of gold and strikes at anyone who dares to get their coins. Either way, you went there.))

When you arrived, there were already piles of coins. You got close to it, and the pile started to shake and started to take the shape of a humanoid girl. — BOO!
