I have no idea if this has been asked before, and I can't be bothered reading through every single post.
Nor am I sure that I should be posting it in this thread ^_^
I'm reading Book 6 right now, and Jake is currently a controller.
When he tries to escape using the ant morph, I get confused.
Visser 3 says, in Book 3 I think, that it's a pity the cat's brain is too small to be infested.
The Yeerk isn't a part of Jake, and therefore shouldn't be able to morph into something as small as an ant.
I imagine the Yeerk would be smushed, or forced out or something of the sort.
I had the same thought at the end of the series when Tom morphs the Snake, surely the snake's brain is too small for infestation.
I think somewhere (though I may be wrong) there's mention of small morphs not being useful for a Yeerk with a morph capable host.
But if I'm wrong, how exactly does this whole morph capable controller morphing into something smaller than the Yeerk in it's brain possible?
