The Thing

Description
The Thing, aka Entity 20, is a creature that looks like a giant fish that inhabits the ocean on Level 7, (the image of it inside the house is for illustrative purposes only).

Tip:
See where she is by the door of the house, so you can see if she's not there anymore for you to go down and look for the exit.

Levels
Her debut is at Level 7, and it will be the only level she will be.
