Geko Swamp (ゲッコー湿地 Gekkō Shicchi) is a swamp on the northwestern portion of File Island.
Geko Swamp is a swamp north of Gear Savannah, and leads to Misty Trees. Geko Swamp seems like any other ordinary swamp, but some say that a palace where the ruler of the swamp resides is hidden somewhere within the swamp.
Geko Swamp is like any other swamp one may see: humid, wet, and noisy. By day it is filled with Yanmamon buzzing around, and by night are wandering Gekomon croaking. However, frequent travelers of the swamp may find a tadpole Digimon named Otamamon hanging around the swamp at various times. This Otamamon is quite rude, and likes to insult others that pass by, even to an extent of challenging travelers to battle. If one can defeat this Otamamon, it is said that Otamamon would summon his Gekomon guards, who would then escort the victor to the hidden palace of the Gekomon. It is said that the ruler of the swamp lives within this palace, and that he has the power to clear the fog of the deeper parts in Misty Trees.
