In SA2B when a chao comes back to life does it keep its color, animal parts, face image, and medal?
In SA2B how many power level-ups do you need to beat the chao Spooky in standard?
No, a chao returns to normal when it comes back to life, however it does keep the characteristics it picked up from the animals.
As for Spooky, it would probably be around 50-70.
