The Grand Gallipoot is the leader of the Growleywogs.
General Guph of the Nome army visited the Grand Gallipoot to request the Growleywogs' help in conquering the Land of Oz. He offered a payment of ten thousand Oz people as slaves, but the Grand Gallipoot demanded twenty thousand. The Growleywog leader and his counselors planned among themselves to conquer the Nomes as well and loot both kingdoms. (The Emerald City of Oz)
