Mr. Grasshopper

"This is an outrage! You are a disgrace to your Phylum, Class, Order, Genus and Species!"

"Say it in English!!

"YOU, Sir, are an ASS!"

~ Mr. Grasshopper arguing with Mr. Centipede.
Mr. Grasshopper is a giant talking grasshopper and one of the many heroes who befriend James in the film James and the Giant Peach. He was once an ordinary grasshopper before he and the other bugs were magically turned life size. He is like a grandfather figure to James. He dresses and speaks like a highly sophisticated gentleman, as he also wears a monocle. He is tall and has the ability to jump real high and fly. His long legs give him speed and strength. The others often look to him for answers, but Centipede does not care for him, which leads to the two constantly arguing. He is skilled in playing the violin. In the film, he is voiced by Simon Callow.

He first appears when a transformed James comes inside their hiding place. When the peach fell in the ocean, James thought of capturing seagulls to use them to make the peach fly. Grasshopper shows an interest in what New York City offers and lends a helping hand throughout the journey. When they get attacked by a mechanical shark, its torpedos break the strings, and Mr. Grasshopper takes James on his back and flies up to retrieve them. The robot shark then fires a couple of torpedoes at James and Grasshopper, but they are saved by Mrs. Ladybug who whacks away the torpedoes with her pocketbook.

Later, when the Centipede accidentally steers the peach off course to the North Pole, Grasshopper furiously confronts him about it and gets the other bugs to turn on him. When Centipede challenges him, Grasshopper sternly kicks him in the face, knocking him out. He later felt remorseful when Centipede jumped in the water, thinking he committed pesticide. When Centipede returned with a compass, he and Grasshopper made up, and the two became friends.

Before arriving to New York, Mr. Grasshopper plays the violin in solace, but James hears and was pleased to listen, after learning it was Grasshopper all along. They are later attacked by The Rhino, and he and the other bugs are separated from James during the attack, but later reunite with James, who had by then transformed back into his normal form. They also helped get rid of James' cruel aunts, Spiker and Sponge. Miss Spider bound them in her string and Mr. Grasshopper spun them around with his feet, making the string cover them completely. After the kids ate the peach, the bugs made its core a home for them and James. In the credits, a newspaper headline shows Mr. Grasshopper as a professional violinist, playing in concerts around the city.
