You can make it a chaos chao or reincarnate it or let it die.
it is not as easy as evolving the first time, because evolving a second time will take much more time. but to quicken the process, keep petting it and beef it up on mushrooms and chao drives. i suggest using doctor eggman or tails to get chao drives, because they defeat lots of robots, which is where chao drives come from. Also, a really good way to beef up stats is to feed them chao fruit. its the blue fruit in the shape of a chao head. they raise all the stats. spend alot of time with your chao. basically, do the same as you did evolving it the first time. except evolving it a second time takes much more time. if you still cant make it evolve, then you probably need to wait till your chao is older. I hope this helped!!
for a chao to turn a year old is 3 hours in the chao garden. but if your asking how many years a chao can live up to, the answer is 5 years. after that, the chao will either die. if it you mistreated it, or it will reincarnate, this happens when the time for a chao comes but if the chao loved you it will reincarnate and turn himself into an egg to be with you. a chao can become immortal after it reincarnates 2 times. but that is the maximum for the reincarnation stage for a chao. if you have a chaos chao of any kind it will not be able to breed at all.
Your chao will age faster if you spend more time in the Chao Garden with your chao.
Here's the truth behind chao: Chao will only die if you completely abuse I'm talking just starve I'm talking you hit it and throw it. Chao if treated correctly will always be reborn if they reincarnate 3 times this is a time where you can then make it become a chaos chao which then it will live forever regardless if you abuse it or not.
Go to the fortune teller in the Chao Kindergarten.
If everyone were to die at the same time, your will would be to no avail.
Everybody dies. That's it.
time passes
Give any chao it's OWN broken egg shell after giving the chao a few skelaton dogs and it will put it on. Now reincarnate the chao twice with the shell on the whole time and after the second reincarnation, it will be a full egg chao(I think). A lot of people say you can only do it with some sort of cheat but I'm pretty sure what I just said works. Good luck. I am actually trying it right now.
Stella dies second i think cause it goes Annie and then she is in the bathroom and she dies right?
In order to get a moon chao,you must get every egg in your Garden(not at the same time), hatch them (in SA2B or the Garden) and put each chao in the garden(not at the same time).It costs 20,000 rings.
Chao will only transform once, if you want a certain type of chao there are certain requirements that you fulfill like giving all the animals or giving only specific animals. When Chao reach the age of 5 they will reincarnate or die if they reincarnate they turn into a baby again and then you can retransform the chao into something different when they die there gone forever.
