I know it is already answered:
Yes you can by giving credit and not gaining money which parodies use in their protection. If I'm animating Macbeth play then I need to credit Shakespeare for example and not gain money from it.
Depends on what you define girly? Does my little pony count because there were alot of that even if they were different genres of my little pony. You might consider your audience or maybe just risk it (You usually lose nothing but time.) and see how they react.

Don't worry about it - as long as you give credit to the source material(s), and don't try and make a buck off it, they'll leave you alone, I'm sure. But you can copyright your animation and vocals... contradictory, isn't it?
As for the content, durr yes. Girly is under-represented across the board. And from over a decade of coming to this site, I found girls make the most interesting and engaging works here.

Oh, wow, really!? Okies, I guess no worries then, and yeah that is really strange actually. I really hope I dont disappoint anyone when/if I make this. Still iffy on my drawing skills, but I feel I will get better while making the animation.
