Aunt Spiker

Aunt Spiker and Aunt Sponge are the main villains in the movie and book both titled "James and the Giant Peach."

After the death of James' parents, they had no choice but to take in James. Instead of caring for him, they force him to do all the work, they beat him, and almost always make him go into his room without dinner.

About Spiker
Aunt Spiker is a tall, skinny and ugly woman. She's probably the older aunt. Spiker is the brains of the two.

About Sponge
Aunt Sponge is a large ugly woman and somewhat small. She's usually the one who beats up James and eats the most. She claims that she is a very beautiful woman, but looks beg to differ.

Scheme
They live in a poor rundown house on top of a rocky hill so they both want to be rich, and they both use the giant peach to get rich instead of eating it. When the peach gets loose, they follow it all the way to New York which is across the Atlantic Ocean. When James tells the cop what they do to him, they attempted to either harm or murder James. They even try to scare James about a monster called The Rhino.

In the end, they are both tied up in Miss Spider's string with Mr. Grasshopper spinning them around, and the cop has them taken away on a crane.

Book
In the book, when the Peach gets loose and rolls, it flattens Aunt Spiker and Aunt Sponge, killing them both, and they subsequently do not reappear at the end.
