Play this game until you recieve a "Life Nut" put the VMU back in the game and take out your Chao you will notice all the items you collected will fly out of the hole. Give a "Life Nut" to a Fully raised Chao you wish to breed and flowers will grow around it place another Chao with it and you will get a Chao Egg!!

    (Note: Sometimes when this is done the Chao which had flowers around will turn back into an egg but dont worry if hatched he will be back to normal except a child instead fully raised)(also this may not work on a certain Chao but most of the time it will work)

    You can make it any color just when your in an action stage and you get an animal you look at the bottom of the screen where all of your animals are located and look at the animals background color (deers background=green)give 20 of those same colored animals to get a chao that color
