Imagine singing the theme song to SCP-1435
You had managed to get to SCP-1435 's cell, in order to test something out. You sat against the wall of the cell, listening to the puppet spit out broken dialog from the deleted TV show.
After a few minutes, and after you signed for what seemed like a 13th time in 10 minutes, SCP-1435 started groaning out the theme to the show.
Now was the time to test your theory.
You started singing with the puppet.
SCP-1435 suddenly went quiet as you continued to sing. Shuffling could be heard on the other side of wall you were leaning against. And then he started grunting the song along with you.
You smiled as you noticed the slight elevation in volume as he sang with you. He was calm and just on the other side of the wall.
Just as you thought.
