ok, so here is the REAL way to get a sonic chao and a nights chao 



Sonic: In order to get the Sonic chao, hatch an egg with any of the hero chao (I chose
Sonic for mine) and feed it nothing but green chaos drives. And raise it with a dark
character also to keep it neutral. Then after it is a level 8 or higher in run and a level
9 or above in stamina (mine was a level 9 in stamina when it evolved) it will go in a chao
head shaped cacoon and it won't make any noise when it evolves, when it hatches, it will
be green will little blue stripes on it's head but after a while, if you keep giving it
green chaos drives, it will turn blue.



Nights: To get a nights chao, hatch it from an egg and give it nothing but purple chaos
drives and also raise it with a dark character to keep it neuteral, then at a level 8 or
higher in fly and a level 9 or higher in stamina (mine was level 9 in stamina like my
sonic chao) it will go in a chao head shaped cacoon and it won't make any nose when it
evolves. when it comes out, it will have an orange emotion ball, purple striped horns and
big aquamarine wings.

(my sonic chao is 2 years old and his name is SonicJR and my Nights chao is the same age
and his name is Spyro)

Hope you enjoy ur new sonic and nights chao :)

#1 in CITY ESCAPE mission 1, go to the mystic melody. you know where it is. if not, run to
the loop then turn left. when you do that, play the mystic melody to make a spring appear,
(do not do this on mission 5, there will be no spring. just 20 rings.) then work your way
up till' you reach a 1-up, get it! then jump into the gray section of the wall. YOUR
FALLING INTO A FOREST DOWN BELOW!

#2 u need to be sonic or shadow. in the normal chao garden, go straight to the corner by
the rocks. home attack it constantly until u fly out of bounds. (all your chao will either
be in the water or 
swimming in the ground. NOW HAVE SOME FUN!!!!!!!!!!!!!!!!1

go to the dark chao garden dig with knucles or rouge and find 2 skulls there is a tomb
stone im between the water and the big brown tree ( the biggest tree ) take the skulls
over there and sit them on top of the tomb stone on each side and they will float!!!!!!!!

If you want your Chao to reincarnate then you have to be real nice to it!! If your not
that nice to your Chao it will die you will know when it dies because of a grey tear
shaped "cucoon" (I have a Chao i wasnt nice to then it became a Dark Chao but i used my
hero character but since i wasnt nice to it, it might die.) =( Now im gona be super nice
to that Chao so it can reincarnate!!! But yes when your chao reincarnates ALL of its
levels go back to zer0, and if you had any animals on it before they will dissapear.

Pick up an animal or chao drive.Drop it right next to the chao(Make sure it dosent take it
from you).WARNING DONT PET THE CHAO WERE ITS STILL LEARNING OR IT WILL CANCEL THE
LEARNING!!!!!!!!!!!

You do not have to beat the game with all a ranks to get amy metal sonic chaos or tikal in
the racing treasure hunting or fighting mode. Just beat the characters as listed in other
cheats posted here to get them in the kart race. I was confused about those first until i
saw the kart race unlock, in which i unlocked easily. All you have to do is beat the route
races (1st mission only needed) with rouge and tails to unlock these.

on the right of the tree with the cage on it in the dark garden there
will be a fence drop a chao in the middle of it and it wil fall in and look like it's head
was cut off!!!

                          the biolizard
           DON"T GET EVREY RING, LEAVE SOME FOR LATER!!
for the first hit, you run from his killer mouth. NOT TOO FAR or he will hit you with his
tail. when he gets tired, grind up the pipe by his mouth and home attack his life support
system. 2nd and 3rd hit he will start shooting energy balls. to avoid them sommersolt the
high ones, and jump the low ones. then grind up the pipe as usual. (at the 3rd hit they
will get faster. 4th and 5th hit he will make ping ball things appear NOT the pipe! home
attack them up to the top and hit the life support system. 6th (last) hit right after you
do the 5th hit, he will make you and the balls have no graity. stay on the outside of the
balls, let about 1/2 of them launch and miss you, the when the time is right, go in and
hit him. ps. the rings will NOT float too.

                          the finalhazard

           A=up and forwerd           B=down and forwerd
at the first hit, there will be 7 pink balls. (annoying arent they) so work your way to
the swolen spot and hit it with a if you are below it and b if you are above it. (DON"T GO
TOO LOW OR IT WILL BE SHADOWS/SONICS TURN AND THEY WILL HAVE AROUND 10 RINGS. SOMETIMES
5)
at the 2nd hit he will have 1 laser. but it goes on and off. make your way through and hit
the spot. at the 3rd hit his laser stays on, so be warned. at the 4th hit, there are 2
lasers that stay on. so be careful. at the 5th hit, there will be thost 2 lasers and
around 7 balls. at the 6th (final!!!) hit, there will be those 2 lasers with near 45 balls
and you only have 40 rings. hit him and TADA!!!!!!!!!
