You are dreaming too much about this things. It is a good fiction, but maybe most of it isn't possible in Spore.
This is why I didn't draw any creatures. Maybe you won't be able to create a Naucean in Spore, and you will cry. 
I realize this but i am taking Will Wright's take on things. Think big and extreme. Do no not limit yourself and think of things no one has thought of yet.
These ideas despite what actually get in actually make others think, and create. Sure i know not all will get in. But one can hope and imagine and then go make some their selves while we wait. Let's say we did this after spore was out and knew all its limitations. Would thats stop you from trying to push them? Find new ways?
In short think out side the box because you can, not because someone says so. I am making this because 1 its fun 2 people enjoy it and 3 hey maybe i could use it for Spore. As you can see the 3rd reason is not the important reason. And i would probably do this even if there was not a game like Spore to do this. But Spore inspired me so i did not think of this before, or have people relating and understanding what i am making.
In short i will not be sad. Because like i said before. I may get sick of the Naucean by the timeSpore comes out and want to create a completely new creature instead.
None of Hydros awesome pictures seems to be working.
Sorry my host seems to be having some trouble with the router. I will have to see whats going on this time.
