I want to question Nepeta's shipping wall being made of dead wriggler blood. More over on the asteroid. In canon it says that she makes it from soot and blood, but it does not look like any blood other than red is used on its first appearance. At the point on the asteroid, she would have access to chalk (as Terezi has some) and with their relationship, it is pretty easily assumed that she would share. Not to mention there are no dead wrigglers on the asteroid (where the picture is from).
Hm, this seems accurate enough.
I DO think the picture was reffering to all of the paint though, I know in the begining it was all red, but maybe she got ahold of different types of blood? I don’t even know. *shrugs*
