I promised this yesterday. Here it comes...! This theory was originally gonna be much longer, analysing the newsletter and images to, but I spent nearly the whole day working on this so I had to cut its length down. If the text to speech stops randomly, just wait. It'll come back. It's just a glitch with the text to speech extension. It's kind of annoying.
Credit to Wikipedia, the Woodland Trust UK, Undertale, and Deltarune for the images. My computer lagged a lot while making this.
