Spiderridingskeleton is currently the biggest mob in the game :o
I do hope Notch makes more singe player stuff...
and adds it to multiplayer ofc.
I want him to get Multiplayer fully functional comparitive to singleplayer, then keep updating content.
But then, updating content is a lot more fun for him, which keeps him motivated. So I guess a balance is required.
But first I wish he'd stop flying around. :I
