The hunt to find the fourth A.P.E.Bot seed
The USB acquired in Singapore contained an image and audio file. The image indicated the final location has a reservation for 4 at 5pm local time.
The Al generated music contained 13 unique short clips, with some being repeated up to 4 times in repetition. While decoding the music, scientists discovered the songs clips had all been parodied by Weird Al Yankovic and this was AL-generated music (lowercase L vs. uppercase i). Identifying the parodied song title and the number of times it was repeated, which indicated what letter to extract from the name led to a final phrase CASA VEGA TACOS.
The final Meetup
Scientists proceeded to Case Vega at 5pm where they met with the final contact who presented them with a locked safety deposit box and a letter. This letter informed the scientists this was indeed the last piece of the seed needed to reboot A.P.E.Bot, but was also when they were most vulnerable, and to take heed and ensure it does not fall into the wrong hands.
The locked safety deposit box
The safety deposit box was locked by a 5 letter combination, which using clues from the location, was found that TACOS was the password to open the lock box. Inside was the fourth and final backup seed for A.P.E.Bot c05678039b92068c along with a letter Doc wrote to himself where he shares that A.P.E.Bot was something he designed to be easily upgraded and installed but to watch out for something that was unfortunately burned off the letter.
