whenever the riquirements are fulfilled. If your chao has a higher level than 15 in any techniqe (Power,Swimming,Flying,Etc) it will be close to evolving/going into its cacoon. And at that point all you really can do is wait for your chao to evolve. If you really want your chao to evolve than you can leave your system on all day, while you are in a chao garden (or all night, that's what i do) by the time you get back, your chao shall be evolved.
P.S. If you want to know a glitch for your chao, than do this..:While holding a animal or a machine part ( the glowing things) go close to your chao, not close enough to automaticaly give the animal to your chao but close so that when you drop it your chao will grab it and throw it back at you, and you can use it again! ( to do this glitch the best characters to use to do this will be sonic and shadow.)
this is how i did it i traded my chao from sonic dx to another chao from sonic advance 2 for the GBA then i traded that same chao to my one of my chao in sonic 2 battle
no codes, just give it only those blue tube things.
To make a choa dark you must be a bad parent. Scole him every once in a while. Constantly feed him dark choa fruits even if he dosent like it.
To get a knuckles choa get a red choa and give it a skeleton dog.Then put a red egg shell on it.Then give it power and fly chaos drives.Make sure it is a neutral and when it evolves you can throw your choa at the wall and the egg shell will pop off.and it should look close to knuckles.
Emblems are awards you get for completing a level,defeating a boss, choa race,ect. There are 180 in the game and are the main goal for the game
You need a shovel and a seed and give the chao the seed and eventually the chao will find a spot to plant the seed
mayby u haven't got any in the garden from story mode
i think because you might not be feeding them anoth or looking after them
If you are talking about Sonic Adventure 2 Battle (or whatever), your choa would get bunny parts and would look like a bunny. If it evolves, the parts may change colours.
stay with your chao long time.and wait it to retincarnate..^_^
well,i say keep colecting choa until you get a choa with a atomatic POW attack wining ability,get wirlwind for sonic (at least pay ten poits) stock up on POW items and tack those things out!
