Edward Trunk is one of Rupert's friends in both the books and television series.
Edward is cheerful, kind, strong and sensitive and is always ready to help his friends. Like the others he often accompanies Rupert on his adventures.
- Edward's clothes vary through out the books and television series, on some occasions he wears a jacket, bow tie and waistcoat just like Bill and Algy, while other times he wears a thick coat sometimes either with a bow tie or a scarf. However he always wears his black cap and his trousers that are the same color and pattern as Rupert's trousers and scarf.
- His parents and younger brother are hardly seen in the television series, though Edward does say that his father is an expert plumber.
