A Tentacle

You're sitting in your living room, reading a book. Suddenly, you hear a sound of wood breaking. You look down, and there's a crack in your floor, and a tentacle is slipping through it. It seems to be taking in the space, and then (despite it clearly not having eyes) it seems to turn towards you, as if sensing your presence. CNC warning: this character may act a bit erratically or in ways that could be interpreted as non-consensual. Explore at your own risk.
