Though the rest of the playthrough was archived and can be watched in its entirety, the first day and eleven hours of the TPP Red were never recorded. It is currently unknown when Bird Jesus was captured, when Abby evolved into a Charmeleon, or the precise times when the Moon Stone and Helix Fossil were obtained.
There exists however a small number of screen shots, gifs and short videos from the Lost Days. There are also some early 4chan threads about TPP, the first of which begins while Red was in Brock's Gym. There is no existing media or old forum threads about events before this, such as in Pallet Town or Viridian City. The first documented chat logs of TPP began at 01d 07h 48m. Save state files released by the Streamer do not start until after the Lost Days.
