It wasn’t there when we took the photo. But all through the night, I could hear a dog pacing the halls. I could picture it, stopping outside each door to cock it’s head and listen, waiting for someone to open their door.
~ The caption for the first photo of the Good Boy.

The Good Boy is a mysterious dog-like creature that was created by Trevor Henderson for his mythos. This monster originated from a post in 2018.

Appearance

This so-called "Good Boy" is a dark dog-like creature. His legs are long and his feet end in stubs. He also has pointy ears. His most notable feature, however, is his face, which has two pure white eyes and a toothless and lipless wide-open mouth. His name being scribbled out in the second post about him implies his alignment to be evil. The caption of the first photo of the Good Boy implies that it can remain unseen somehow, as the person who took the photo commented that it wasn’t in the image when they took it. Despite his name, Trevor said he's not a dog.

Personality

Not much is actually known about this mysterious dog-like creature. The caption for his original photo suggests that it enjoys wandering in random places (the description suggests this place could be a hotel or residential area), stopping by each door to carefully listen and wait for someone to open the door. It is unknown why it does this; if this is some sort of hunting tactic, or if it is simply just curious. None of its goals are currently known right now.
