Sometime later, Spiker and Sponge discover a peach on a withered old tree, and watch it grow to immense proportions in a matter of seconds. Spiker and Sponge use the giant peach as an attraction, making lots of money as James watches from the house, not allowed to leave or play with the other children. That night, Spiker and Sponge send James outside to pick up the garbage dropped by their customers.
Later, when James escapes on the giant peach, he is followed by his two persistent aunts all the way to New York, apparently somehow managing to drive their now crushed car under the ocean and reach New York covered in seaweed and crabs, where they try to convince the authorities that James is a liar and that he be released to them. However, James, now no longer afraid of his cruel aunts, stands up to them and reveals the truth about their horrible treatment of him. Unable to believe that James dares to stand up to them, they furiously attack him with firemen's axes until the sudden reappearance of the insects. He then ties them up with Miss Spider's thread, and the police take them away.
In the book, Spiker and Sponge are both crushed to death by the Giant Peach. In the 1996 film, they survive and pursue James to New York City in their rattletrap car (in the Ice World, James and Miss Spider see a shipwreck with figureheads, having a terrible resemblance of the two aunts). Upon arriving in New York, both are soaked as if they had been driving their car across the seabed. They attempt to kill James but are tied up with Miss Spider's silk and arrested.
