If someone saw this image 15 years ago they would have made it into a creepypasta and multiple people would hang themselves claiming "the blue man told me to"
My theory is that Chapter 7 Side B is Undertale.
Because of what Gerson says.
Undertale is already programmed, so Toby could just copy+paste it into DR Side B.
And that's not all. Sly Toby put NOELLE into the 10th anniversary version of UT. Coincidence? I think not!!
