Wait wdym he reposted? Can you give link

Ok well it could be any game we just need the creator of this meme to clarify cuz it could either be terraria or Minecraft or maybe even another game

He is saying that the world is not flat because if it where then there would be slimes because in Minecraft when you create a super flat world it makes slimes appear everywhere. Plus like i said terraria worlds are not flat

DUDE! IT IS MINECRAFT NOT TERRARIA
Plus why do you think that the terraria worlds are not flat
