Scary note Ideas

[Cranky Old Man]

Can anyone give me on an idea for a creepy note like a three or four line poem thing because a brute drops a note and then a key is hidden and I want a good creepy not saying he hid it.

Also I want to know how to make the key spawn randomly instead of the same spot. I saw this done on the darkroom but it looks confusing and want it simplified.

Any advice or help appreciated.

So in your custom story, the grunt is a poet gone mad?
...or is there even a story, or an explanation for the grunt?

"I am a generic monster.
I write generic verse.
God knows why I'm here.
BTW, here's a key."
