Chao Fever

Never Ever hit or attack a Chao
Never throw your chao around.
Pet your chao every once in a while
Do not pet a chao too much or it will become spoiled! This is something you do NOT want!
Feed your chao by hand until he is full ONLY when he is in childhood. Doing that after evolution can spoil the chao
If a Chao is skipping or running towards you(It likes the character you're using alot) pet it ONLY ONCE.
And for every good deed there is a reward. Be nice to your chao and when they will reincarnate when they die.
