 What's the biggest backroom's entity? Well, to answer that, I would have to scroll through the wiki for hours on end and compare sizes of creatures over and over until I find the biggest one. Oh, that's my job, I forgot. The Strider is a huge creature in the backrooms, which is a large eye-shaped being that lives on level nine deep inside the suburbs. These things have six eight feet long arms, which propel them to be about eight feet tall. They can run really fast up to 100 miles an hour. And while eight foot tall does sound pretty big, it's nothing compared to the actual biggest backroom's entity. La Camiloa is an entity that lives inside the murky waters of level 4,000. Takes the appearance of a humanoid made out of stone and it's set to be around 100 feet tall. It's extremely rare to encounter it though, so that's pretty good. Anyways, the actual biggest entity is Broogly's bald head.
