In his cave, the giant identifies himself as the Big Friendly Giant (or BFG for short) who blows dreams into the bedrooms of children at night, while all the other 9 giants are vicious, child-eating beasts. Because the BFG refuses to eat people or steal food from humans, he subsists on a revolting vegetable known as a "Snozzcumber", which is all that grows in Giant Country. He explains that he took her so she couldn't tell anyone that she had seen him and start a giant hunt. Sophie and the BFG quickly become friends; but Sophie is soon put in danger by the sudden arrival of the Bloodbottler Giant, who suspects the BFG of harbouring a human after hearing him talking. The BFG tricks the Bloodbottler into eating the Snozzcumber to repel him from his cave, during which Sophie is almost eaten. The BFG makes her a new dress out of her blanket to replace her heavily soiled nightgown. When Sophie announces she is thirsty, the BFG treats her to a delicious fizzy drink called "Frobscottle", which features bubbles that go downwards rather than upwards, which causes the drinker to flatulate; this is known as "whizzpopping" to giants, and causes the drinker to soar and shoot around the place.
