3 to 4 hours
it takes a little while for chao to get older but you have to care for it and after a while(depending on which character you use hero or evil)then the chao will go to the stage of chao death.
Here are some great tips for raising your chao... 1) Never abuse your chao they hate this and the can die faster if you do 2) Never wake your chao up, a sleepy chao may not be so willing to mate even if it is given a heart to eat 3) Love and pet your chao a lot when they began to follow you and come when you call that means there is 100% chance that the chao will reincarnate 4) Never take food away from your chao they will cry if you do 5) If your chao gets sick take him to the Chao Doc. Chao can become sick even if they are well cared for 6) Give your chao food remember a hungry chao is not a happy chao and he will let you know it too 7) Chao like treats give them their favorite foods, you can find out what their favorite foods are by taking them to the Chao Doc. Remember a Hero chao will never eat Dark chao fruit and a Dark chao will never eat Hero fruit However a Normal chao will eat both. 8) When reincarnating your chao make sure you give it all 21 animals and no chaos drives 9) Once you get your Chaos chao treat him well although it is true that Chaos chao can never ever die no matter how you treat them 10) And also know that Chaos chao can not mate and they can take on animal parts however many people don't know this a Chaos chao can take on the flame of the half fish I have tested this myself but you have to do it before it becomes a Chaos chao you do this by giving the half fish to your chao last out of the 21 animals if it takes on the flame it will still have it when it becomes a Chaos chao if not oh well you can not redo it. for more on this just ask me and I will be more then happy to help.
Press A on the egg to make it hatch faster!
Reincarnate a Flame Swordsmen. It might take a few tries
3 to 4 hours
Your chao needs to be 5 years old to reincarnate you must wait in the chao garden at least an hour or more for it to turn a year old.
I take it you mean a Chaos chao. Reincarnate it twice,then on the 3º life give it one of each all 21 animal types (no drives).Wait for evolution.The type of Chaos chao you get depends of it's alignment.
5 years.
"Like most things, Chao can die... A Chao's life usually lasts about 7 - 8 hours on the Dreamcast. On the Gamecube the Chao has an age. When the Chao reaches 5 years old* it will reach the end of its life, and it will cocoon and die after that. But, if your Chao liked you, it will reincarnate and leave an Egg. If it didn't, then sadly your Chao will not reincarnate and will be gone forever. *A Chao Year on the Gamecube lasts around three real life hours. If you care for your Chao extra well, it's years will take longer. Likewise if your Chao is unhappy and get hit alot, it will take shorter to age and in turn, die quicker. Also note, that some studies show that when a Chao breeds with another Chao, its lifespan decreases. The age of your Chao is shown in the Medical Chart with the Chao Doctor (in the Kindergarten)" - Chao Island
That depends on how you've treated them. If you have been very nice to your chao, they can live for up to twenty hours, I think. If you were very mean to them, not only will the chao live a very short life, but it will also die, rather than reincarnate, and you will have lost it forever.
Wait patiently in the chao garden for a very long time make sure you take care of your chao of course after a long time take it to the doctor to check its age it should of gone up if not wait more.
Give your chao lots of dark fruit (which can be bought in the Black Market), after it looks dark enough stop and wait for it to evolve. After it evolves do what ever you want to do with it (besides hurt it or take fruit away from it), treat it nice. Then wait for it to recardinate (you'll know when it recardinates because it will go into a pink cocoon). If it goes into a grey cocoon it will die. After it comes out the cocoon it will back in it's egg. Rehatch your chao then before it evolves again give it lots of dark fruit and one of every animal in the game. After it evolves you should have a Dark Chaos Chao (Devil Chao).
A chao evolves in 2 ways. To get a dark chao it will evolve when you have made it have a dark wing. To get a hero chao then it will evolve when you have made two balls on his head connect.
it takes a little while for chao to get older but you have to care for it and after a while(depending on which character you use hero or evil)then the chao will go to the stage of chao death.
