6)Aurora
7)Belle
8)Ariel
9)Jasmine

She does work hard emotionally to get what she wants across but not much more happens physically.

I stand by what I said before: She always backs out of her chores whereas the others do them as well as they can.

Mulan saved China and gets her dad tea
Cinderella was constantly tidying and cleaning
Snow White was always do things for the dwarfs
Pocahontas and Tiana I don't know I never seen the films

^^Then how can you make a pick? That doesn't make sense, at least IMO.

Anyways, even if Mulan got out of her chores, it's because she was late. She works very hard to be a good soldier, and I imagine on a normal day she'd work hard on her chores (with a complaint or two, I admit).

I can just see Poca blowing off the planting or harvesting to stand gracefully atop a cliff and contemplate life or talk to Grandmother Willow about a strange dream she had.

Why did so many people pick Tiana? Them movie talks about how she works too hard.

Oh, after seeing someone picked Tiana, I'm quiet calm about the results. They'll be unfair. And it's okay...

I can't believe people voted for Tiana, she's the most hardworking IMO

The others busted their asses cleaning or being in the army!! She just stood around and looked pretty!!

She basically had the freedom to do whatever she wanted. She does work here and there but not so often.

I agree with DreamyGal.

she jumped off the cliff
i dnt consider tht hardworking

She really did nothing, she played around a lot, but didn't really do anything physical.
