The Fountain of the Earth (土の泉 Tsuchi no izumi?) is one of the fountains that nourishes the World Tree.
The Fountain of Trees is located inside of the Land of Fountains. It is the third fountain that Cure Bloom and Cure Egret recovered from Dark Fall. The fountain is full of bogs and swamps.
The inhabitants are brown spirits. The one responsible for drying the fountain and guarding it was Dorodoron .
This fountain was recovered in episode 20 after his defeat. The inhabitants returned to the fountain and everything returned to normal.
