Which Roald Dahl book features a giraffe, a pelican and a monkey who run a window-cleaning company?

The Roald Dahl book featuring a giraffe, a pelican and a monkey who run a window-cleaning company is The Giraffe and the Pelly and Me. It was published in 1985 with illustrations by Quentin Blake.

The story follows Billy, a boy who dreams of owning an unusual sweet shop. Instead, he meets the animals of the Ladderless Window-Cleaning Company: a giraffe with a long neck, a pelican with a large bill and a monkey who climbs expertly.

The title’s “Pelly” is short for pelican, while “Me” refers to Billy, the human narrator. The animal trio’s different physical abilities make their business possible without ordinary ladders.

The book is shorter and more illustrated than Dahl’s longer novels, but it uses his familiar combination of wordplay, comic danger and imaginative creatures. Quentin Blake’s energetic drawings are especially important to the book’s visual storytelling.
