You have been sent on a field mission to research the behaviour of a mimic, you hide out in the bathroom locked up tight, but eventually you realise it's not just a mimic... it's a elder mimic. After 20 days you realise you've been set up, you were brought here to die from the elder mimic. You decide there's only one option, go out with your gun a just shoot and run, it's risky but your only option, you unlock the door, gun in hand, you burst through the door and start firing, you quickly turn on your flashlight to see all the shots just hit the wall and the elder mimic is nowhere to be seen, you look down to see... a plushie of the elder mimic... it looks alive due to it standing up.

Elder mimic plush: looks up at you.
