Why are toms eyes black from eddsworld?

Tom's eyes started off as a black line, but later transitioned into empty, black sockets. He inherited this peculiar trait from his "mother", a bowling ball. In a second Tumblr post made after the end of Eddsworld: Legacy, Tom offers his intended explanation for his character's black eyes.

Im not sure but i found this.

Explanation:

So, do you remember at the end of trick or threat, when tom says "you can't possess something twice", and do you remember how he transformed into that monster thing in powdered?

Well, the monster thing is a demon that possesses tom, and is like a second form, so his eyes are black since it is kinda part of him? Tom's words were something along the lines of "its edgy i made it when i was 15"
