This is true, HOWEVER, that is not how you get the chao types.
To get a hero you must use Tails, Sonic etc. and you should treasure it by patting or the craddling thing I don't know (basically make the chao love them).
To get a Dark Chao, use ANY character and abuse it, buy throwing it, jumping on it and stuff...
They only last till 5, unless you allow them to transform into a hero or dark chao.
He died of old age.
It would be pretty cool if there was.
But there isn't you friend is just a dirty liar!(no offence)
