D.Y4: The END of Princess Peach

In the Game Theory video posted on 10/06 at around 16:00, the intro from D.Y3 was substituted in place of the standard intro. This is most likely used as a catch up for players who have not yet seen the video on the tenretni olleh channel.

A cipher was hidden in a book at 05:07. The book had a picture of Princess Peach in an 8-bit style with the text "GWNWWGRC WHFE ZW MCHLEZY SDTBBPW WT" above it. The cipher was decoded as a Vigenère with the key "TOADSTOOL". The plaintext "NINTENDO LORE WE TOTALLY PLANNED IT" appears to be in reference to the Nintendo theme that has prevailed across the ARG thus far.

The video shows a webpage (0:15) referring to the "Bowsette" trend. While they make this reference, bottom left corner shows the following categories:

• +whydidyoureadallthese

• +theresnothingherebutwords

• +whatareyoulookingfor

• +somesortofclue

• +ifonlywehidonehere

Below this, there is another subtopic that is called "scarlet_clupea_harengus" which is a synonym for "red [scarlet] herring [latin name]".
