TSTP S3E9- The Bite
Did you hear that? Was that the fireworks? Billy said the Monster can see Eleven. I think he is right and it has found the kids! Seconds later the creature’s vast tentacles burst through the walls of the cabin. El uses her considerable power to push the Mind Flayer back over and over. Her friends fight to help her. They shoot and chop at the vicious thing. Ultimately they succeed and the Monster retreats but not before it manages to take a bite.
