Chao only evolve twice, so there is no third form.
No, on the third lifetime of the chao it must be fed precisely 1 of each type of animal or it will not become a Chaos Chao.
Chaos Chao is available if you give your chao all the animals that you can get in stages whether there going to be a hero or dark chao if you do these they will change to a chaos chao which in this form can never die and it won't turn into a baby but the looks of your chao will not show any animals and it can't mate and if your chao has any expressions on its face smiley or anything else it will NOT show on your chao anymore but its worth getting. By the way to get the ultimate chao you have to do those steps in sonic dx.
First your chao must have reincarnated three times, when it's a baby give every small animal to your chao and when it grows up it will become a chaos chao. What animals it received in previous lives doesn't affect the chaos chao process, just make sure that it receives one of each animal during its infancy in its third reincarnation.
Buy the black egg from the shop in the Tiny Chao Garden on Sonic Advance, SA II, Sonic Pinball, and SA III for 20,000 rings. Then send it to SA2 with the GC/GBA cable.
You can obtain a Gold Chao in Sonic Advance 1 and 2 by finding it in The Tiny Chao Garden, in the shop. There is a chance that there will be a Gold Chao. You can get other Jewel Chao, too. You can also transfer the Chao to Sonic Adventure 2: Battle by using the GBA link cable to the Gamecube or Wii. And also you can get one in Sonic Adventure DX but I'm not sure how...I don't own the game sorry. D: But I hope that helps!
A "Blitz" Chao is a Two-Tone White Chao. You can get this Chao by breeding a White Mono-Tone with a Normal Chao.
* Step 1:Acquire a Chao egg from your garden or by mating two Chaos. A spotted egg will produce a Chao that has the potential to become a Rainbow Baby Chao. A colored egg will only change the ball on the top of the Chao's head. * Step 2:Hatch then feed the Chao red Chaos Drives until the Chao's power equals ten. The red Chaos Drives will increase the Chao's strength by eight points for every ten the Chao is fed. Get the red Chaos Drives by using Tails or Dr. Eggman to collect them. * Step 3:Make the Chao a Hero Child Chao to create stripes that will help form the rainbow. To make the Chao Baby a Hero Child Chao, have Sonic, Knuckles or Tails pet, hold or cuddle the Baby Chao. * Step 4:Create a Dark Child Chao instead of a Hero Child Chao if you desire. It will have stripes its whole life, unlike the Hero Child Chao. To create a Dark Child Chao have Shadow, Rouge or Dr. Eggman pet, hold or cuddle the Baby Chao. * Step 5:Repeat these steps three times. This will result in a full, dark power Baby Chao with stripes that resemble a rainbow.
You'd have four different options: * A gold chao * A silver chao * a gold chao with silver highlights * a silver chao with gold highlights
Your chao will age faster if you spend more time in the Chao Garden with your chao.
Chao CAN mate with each other.Ok,so one of your Chao has flowers blooming around it.In order to make a Chao mate with the Chao that has flowers blooming around it,you need to put another Chao next to the Chao that is ready to breed.Sometimes,a Chao might not like the Chao mating so then it goes away.Or you might be trying to breed a Child Chao with a Baby Chao.Baby Chao cannot breed with others.Only Child Chao with Child Chao.And the last reason why you can't mate your Chao is probably because you are trying to breed a Child Chao with a Chaos Chao.Chaos Chao cannot breed.Sometimes a Chao is already near the Chao mating.So if it likes the mating Chao,it will walk up to it and they will breed.
It is possible as long as it's passed stage two as i call it, give it ONE of each animal and raise it's stamina it should form one!!!
He would either become a "Death" Chao or a "Life" Chao With Unlocks you a Grave yard Chao Garden of a Heaven Chao Garden with is amazingly Fun :)
