Role in the film
In the beginning of the movie, James is seen living with his parents in a little house by the sea where they celebrate James' birthday and look at the clouds where James spots the tallest building in the world to which his father shows him a travel guide of the tallest building in the world which is The Empire State Building in New York City where James' father tells James that's where they're going and that there's lots of kids in the city and New York City is a place where dreams come true. However, his parents are killed by a rhinoceros from the sky and James is sent to live with his two evil aunts Spiker and Sponge who abuse James and make him work day and night. One day after James finishes chopping the wood for his aunts he begins to look at his travel guide of New York City when his aunts come over and snatch the travel guide away telling him that he's never going there because he'll always live with them and that he shouldn't dream because that's what got his parents killed and then they rip up the travel guide and order James to get back to work. Later that evening as James returns from doing his work his aunts tell him that they've already finished all the dinner so James steals a bag of food crumbs from the garbage to eat. As James goes into his room he notices a spider spinning its web and tells it that he'll be its friend and begins to sing about his dream to go to New York City (My Name is James song). The next day Spiker and Sponge find the spider in James' room and try to kill it but luckily James takes it outside before they can and tells it to get away from this place and that he wishes that he could get away too.
While rescuing a spider from being squashed by his aunts, James meets a wounded Confederate soldier who appears with a bagful of magic green "crocodile tongues", which look like twisty bugs and are supposed to make his life better. The soldier warns him not to lose the "tongues" and magically disappears. When James is returning to Sponge and Spiker's house, he trips and the "tongues" fall into the root of an old peach tree, affecting it and its inhabitants in amazing ways.
One peach is soon found on the tree, and it grows to immense proportions. Spiker and Sponge uses the giant peach as an attraction, making lots of money as James watches, from inside the house, in tears. After one night of success, James is sent to pick up garbage. While doing so, he grabs a chunk of the peach as a "crocodile tongue" enters it for him to eat. James ventures into the giant fruit were he finds and befriends a group of anthropomorphic invertebrate animals (who are all much larger than his small petite frame) who also dream of an ideal home (Mr. Centipede, Mr. Grasshopper, Earthworm, Mrs. Ladybug, Miss Spider, and the Glowworm). As they hear the aunts search for James, Centipede manages to cut the twig holding the giant peach to the tree and the peach rolls away to the Atlantic Ocean with James and his friends inside it.
They use Miss Spider's silk to tie a hundred seagulls to the peach stem, while battling against a giant robotic shark, allowing them to fly their way to New York City. While flying, James and his friends eventually find themselves hungry and soon realize that "their whole ship is made out of food". After gorging on the inside of the peach, Miss Spider, while using her web to tuck in James, reveals to him that she was the spider he saved from Spiker and Sponge. James then has a nightmare of him as a caterpillar attacked by Spiker, Sponge, and the rhino. Awaken, he and his friends find themselves in the North Pole, lost and cold. It is then revealed that the Centipede has never traveled the world and has only lived on 2 pages of the National Geographic. He and the Grasshopper have a fight and the other bugs lose faith in ever reaching New York City. Grasshopper mentions that the only way they can navigate out of the Arctic is to have a compass. Centipede overhears James's mention that ships have compasses, dives into the cold frigid waters where dozens of ship ruins are found. After finding a compass he is captured by the haunted remains of the ship's crew. James and Miss Spider rescue him just in time. Now knowing their way to New York, the bugs tell James that he and them are family. As the group finally reach New York City, a storm brews and blows the compass away. James tells everyone to climb onto the peach stem and hold onto the seagull strings. The rhino appears riding with the clouds and James learns to face his fears before the rhino strikes the peach with lightning before it disappears. He falls into the peach and the bugs fly away from it. James coughs up the "crocodile tongue" and returns to his live-action form, finds out that the peach is on the Empire State Building dripping juice on the citizens. As he is rescued by crane men, he discovers that his aunts found him and plans to take back James and the peach. James tells everyone his adventures and reveals Spiker and Sponge's abusive behavior towards him. They attempt to kill James with fire axes while the policemen try to protect him. The bugs are able to fly back down to rescue James in time and tie up Spiker and Sponge, using Miss Spider's silk. The police have crane men to take them away, while James and his group are praised as heroes.
As thousands of children gobble up the fruit, the peach pit is made into a house in Central Park, a while later. James now has all the friends he wished for by telling them his courageous adventures with the bugs becoming his legal guardians. It is then revealed that the narrator is the Confederate Soldier. While finishing the story, he grabs a "crocodile tongue" and moon blinks at the audience.
- Paul Terry got bitten by the spider during the shooting of the spider scene (in which Miss Spider is portrayed by an actual spider). He never acted again after this.
