Now normally I wouldn't think twice about something like this but this was the very first Minecraft related thing I've seen even before I knew what the game was or the gameplay aspects of it... but I'll spare you my past with the game.
The Video: I remember the video taking place inside a castle or dungeon of some sort because it was made of grey blocks. It was multiplayer because there were two people. The player in the video went up a spiral staircase into a bedroom like area but one of the walls was made mostly of iron bars and looked into a hallway. In the room a creeper spawned and it was paying attention to another player in the hallway and trying to pathfind to the player through the bars, but not exploding... Even if the player stood right up next to the bars... Now idk if they were using a texture pack or not I'd like to say they were but...I'm not sure...
Other things to note: -I'm not sure if it was an adventure map or not -I looked through some of the yogcast with no luck but I'm not ruling them out either since they were pretty popular at the time -it goes without saying this was Java -the sad thing is I'm not sure if the video is even up on YouTube anymore...
