Ok, so I found this Alien Language letter in Lethal Inspection and decided to decode it. This is a screenshot of it:
This is what I got when I decoded it:
"Need extra cash melt donky our old unwanted human swephy top dolar"
Doesn't make much sense to me...but maybe that's the point...? I'm not sure. What do you guys think? I could have messed up on a few letters (because her thumb is covering part of it, and a few other parts are hard to read). Anyway, if anyone comes up with a more logical outcome, feel free to post it here.
