Disney Animator dolls are awesome. As explained by toyjunky they have a much more expressive face and are rather unique compared to the standard Disney toddler dolls sold at other stores.
There are also special editions of the animator dolls like Ursula and uber special Princess ones that have lights and more elaborate outfits.
And then there are the customs people make of these dolls that are sooo beautiful...
Originally Disney store was the only place you could get them; however, I did notice in a Target recently that they carry the animator dolls. But I think this target was unique as I haven't noticed the special 'disney' section in every target. This Target had a special Disney section adjacent to the toy section that was all 'disney'. So it was sort of like a mini Disney store inside of Target.
