"You spelunk through a desert cave as you meet a sleeping lamia wrapped around a chest. What do you do?"
Being the Clever Dan that I am, I carefully reach over her and put a few drops of my blade oil onto the hinges, trusting it to stop any squeaking. Careful not to bump the lamia, I start to carefully open the chest.
As is to be expected in these situations, things do not go as planned. Little did I know, the chest is actually a Mimic's TARDIS-house. As the top opens, she pops out and pulls me in. I let out a surprised yelp and the top slams shut with a lound thunk, waking the lamia for a second.
She mutters a sleepy, "Huh?" and rubs her eyes. She takes a moment to look around before deciding it must have been her imagination and lays down, going back to sleep.
