How many of those cubes do you think there are, mister? If you perma-morph one more time I'm leaving you like that! No, but you could literally just get the DNA from your parents and "create" yourself again. And you don't need to intentionally perma-morph, by my recollection, the character in question just treated his original form as just another morph he had under his belt, and the bird was his "true" form from them on.
