For context, I had an idea for some sort of Undertale AU inspired by Over The Garden Wall earlier today called "UNDER THE MOUNTAIN'S CORE", where a kid ends up lost and somehow ends up underground in the process The protagonist is called "Echo", a lost teenager, who, with the help of a friend they find underground called "Flowey", will hopefully end up back home…

… While "The Beast" is stalking their every move. Waiting for the protagonist to start hurting somebody in any shape or form, so that it can strike. (Can you guess who this is meant to be from that description?)

Idk if I'll make more mockups of this, I just wanted to show the general idea for this since it was in the back of my head all day, and it seemed like a fun thing to make
