Frobscottle is a drink found in Giant Country, and makes its only appearance in The BFG. It is the only drink that is known to be consumed there.
Frobscottle is a green, fizzy drink, with the bubbles in the liquid flowing downwards, instead of up, as in common fizzy drinks. The bubbles flowing downwards, will cause the drinker to let out a very loud "whizzpopper". The "whizzpopper" that is let out will cause the drinker to fly upwards for a short period of time.
