I've played the sonic games on my old sega when i was little. and, of course, i had fun for a while and then kinda threw it away. But now these new Sonic games for gamecube and such like Sonic Adventure 2 Battle i've seen so many kids r playing has a new feature--- Chao. Those cute little walking blue things or whatevr r so weird... just weird enough 2 make a perfect zoo in zt!!! i have no clue whatsoever how 2 make 1 of these but once i saw one a few days ago while some 8 yearold or something was playing; i just laughed out loud and thought about zt.
