I was rewatching this and If it wasn’t said, I think yellow guys name is David because on the second episode. The box thought yellow guy was dead and on the tombstone it said David and in yellow guy overalls, it has a letter D on it. Don’t know if it was said in previous episodes or conspiracies
My favorite one just might be the lost episode because of all the chaos that happens and the extra lore, and most of all because the songs are better than all of the TV series' songs
