He also appears in another novel, Danny, the Champion of the World, in which he is introduced as a folkloric character. The name suggests he likes to smash maidens, but it is never confirmed it could mean he smashes them with his teeth. But we learn that he is also a coward when he has a trogglehumper and when he's captured after Sophie sticks him with a brooch.

That means,’ said Sophie, ‘that somewhere in the world, every single night, nine wretched people get carried away and eaten alive. He rolled the huge stone to one side and said, ‘Peep out over there, little girl, and tell me what you is seeing. Despite looking disgusting and towering over even the BFG, Fleshlumpeater is not exempt from imperfections.

Believing that he intends to eat her, Sophie pleads for her life, but the giant laughs and dismisses the idea. The only other such longstanding partnership I can think of in English children’s literature is with author Jacqueline Wilson and Nick Sharratt. Before letting the BFG leave peacefully, Fleshlumpeater suddenly grabs him with his two gigantic hands and tosses him high into the air. The nightmare that he gave Fleshlumpeater is of the story of Jack and the Beanstalk, and Jack is the only human that giants fear.

In The BFG, more than eighty changes were made, including changing or removing references to colour in people (such as changing "Something very tall and very black and very thin" to "Something very tall and very dark and very thin", "the flashing black eyes" to "the flashing eyes", "their skins were burnt brown by the sun" to "their skins were burnt by the sun", "white as a sheet" to "still as a statue", and removing "His skin was reddish-brown"), changing "mother and father" to "parents" and "boys and girls" to "children", and changing "Esquimo" to "Inuit", "Sultan of Baghdad" to "Mayor of Baghdad", and "man-eating giants" to "human-eating giants".Tourists come in huge numbers to watch the giants in the pit, who are only fed snozzcumbers; they receive an unexpected welcome snack when three drunks manage to climb the safety fence one night and fall in.

However, on the way home, the BFG has the idea to give Fleshlumpeater the nightmare that they had captured in a jar in the dream field.
