Fatso the Fat-arsed Wombat was the unoffical mascot of the the Sydney olympics. He was hated by the organising committee but loved by everyone else. He became so popular there is now an official statue of him in the olympic village.
I loved Mystery House! I never found the treasure, I think I got stuck in the attic trying to remove a brick? I remember when you typed in any 'bad' words, the program would say goodbye and close down.
