Yeah, The Decision has complicated the issues with the acquiring ability. But that book itself confirmed the Andalites realized that the Anirmophs themselves had more morphs than their own Andalite spies. So the Animorphs are really the ones pushing the boundaries of this piece of techonolgy.
Has anyone ever done a count on which animals were unaffected by the 'drowsy' effect that comes with the acquiring process?
Oh! And here's another question.
I always wondered, say in the case of Cassie, if she wanted to morph back to a catterpillar, would she be unable to due to the metamorphosis into her butterfly morph... Has the metamorphed DNA remain in the system, too?? And if so, would the new morph be preserved?
