Describe old green grasshopper

Old-Green-Grasshopper is wise and cultured, and he serves as a moderating force amongst the peach passengers. Even when disputes erupt between Centipede and Earthworm, Old-Green-Grasshopper manages to remain levelheaded. Whenever James tries to solve the problems that the group faces, Old-Green-Grasshopper is a stable figure who proves willing to help James with whatever he needs.

This venerable "short-horned" grasshopper is also a talented musician who surprises James with his abilities; he is able to use his own body as an instrument, producing rich melodies that call to mind the sound of a violin. At the conclusion of Dahl's novel, the Old-Green-Grasshopper becomes a member of the New York Symphony Orchestra, where his playing earns great admiration.
