If you breed a neutral hero chao with another neutral hero chao and want to make it a sonic chao will it work

no it won't u have 2 have action replay --------------------------------------------------------------------------

It should if the baby comes out as a normal child chao...If you want it as a sonic chao give it lots of green chaos drives or nimals that increase running, and keep the running level about 10 more than stamina level...I suggest 5 stamina and 15 running...It mayt ake long, but it's worth it.
