gold might be the one who created the note block universe of Episode 29 why? because in Episode 29 of avm we can see that they arrive in a minecraft world and gold is locked in a minecraft world and if he was in a world of music it is because his dream was to become a musician/player like we see it in Episode 30 where he was happy with the singer and when gold trying to get out of the Minecraft stuff crumbs of him spread all over the world and the world had to take a little of his dreams until he gets absorbed and his dreams and minecraft multiplied together and gold would therefore have tried to survive in this world and it would therefore be him who would have created the portal of Episode 29 or he therefore arrived in the nether and he always tries in return home even though his father was not far from him spoiler:I made it all up🤣
