Aunt Fanny

Aunt Fanny (or Aunt Fan as she was called in the UK version of the film) is a supporting character in Robots. She is voiced by Jennifer Coolidge.

Physical Appearance
Aunt Fanny is a large, red and white colored, snail-like robot with dark blue eyes. Her most notable feature is her enormous backside, which resembles a snail's shell. It is held up by a single wheel and can be used to store things, or even other robots. Her front end is much smaller than her rear; and sports arms and legs just like all the other robots. She wears a very large hat-like object on her head, which is adorned with numerous decorations.

Personality
Aunt Fanny is a kindly, generous, motherly figure toward broken, "outmoded" robots. She took in Fender, Piper, Crank, Lug, and Diesel when they had nowhere else to go, allowing them to stay in her boarding house, making them her possible adoptive sons and daughter or adoptive nephews and niece. She instantly takes a liking to Rodney, and comes to say goodbye to him when he wants to return to Rivet Town. She is known for being "a little artsy-fartsy," a reference to how prone she is to farting. In a contest among the "Rusties," wherein they made arm farts, she revealed her gassiness, as she actually farted, killing a nearby streetlamp. Aunt Fanny also has a sentimental crush on Bigweld. She seems to be a pacifist, as she states at one point in the movie that "Fighting never solved anything". However, this could be false because in the final fight scene, she is shown knocking Madame Gasket's henchmen aside with her rear end which is proven to be her weapon. At the end of the film, she is shown dancing with Bigweld in Rivet Town.
