I feel like this is possibly one of the most overlooked things in Petscorp so far

I don't have much to contribute but the moment he enters the scene in Petscorp 1 is kind of a red flag It is in a stark contrast to, basically everything else before he enters the newmaker plane, or whatever the dark glitch world is called. I believe that this alone is some indicator that (aside from the note that came with the game) Newmaker was intended to go to this plane as it blends well with the rest of the environment. This also leads me to consider that the entirety of this Newmaker plane was the original game (if the notion of it as an unfinished game is to be followed) but assets were converted to be more child friendly and so on, but Newmaker was not redesigned. It looks like a zombie, something undead. When it's walking horizontally, the shape of it's head resembles even more like a skull.

I'm sure we've all thought of this next point at least once (or i'm just really gutter minded) -- Does it's "mouth" kinda look like a vagoo? If this has ANY validity to it, it could have some more implications to birth/rebirth and the protagonist's role.

Something likely irrelevant that kinda stuck out to me was that it's walking animation has only two frames and the character has no animations outside of walking - as far as we know and can see,

Like I said, I don't have much on the subject but I would like to see a bit more discussion on it, and I believe there's plenty of room for it. The appearance of the avatar seems just like something that could have considerable implications and be under our noses the whole time. By the end of this I'm sure we'll figure out what it is, but I'm more concerned as to why it is what it is. We know that the inhuman animal/plant/inanimate object pets are in the gift plane, and so far the human "pets" are in the Newmaker Plane (with the exception of Toneth). I want to re emphasize that - the human pets are found in the Newmaker plane, which matches Newmaker's appearance and the only other characters that come close to resembling Newmaker are Marvin, who is only seen in the Newmaker plane. (There is also Pen, however the resemblance is only in color, which Pen pulls off in the Gift Plane because of her innocent and cartoony appearance, once again, in contrast to Newmaker's.)
