The Moonpool is a small pool, situated at the bottom of a stone hollow, a certain distance from the Clan territories. On one side, there is a steep cliff with water flowing out from a cleft, feeding the pool. There is an underground stream leading out of the pool, which flows into the lake and marks the border between ThunderClan and WindClan. A narrow path dimpled with ancient pawprints leads down to a flat stone "beach" next to the pool. For sharing tongues with StarClan, the medicine cats lap up a few drops of water or they touch their noses to the water.
In The New Prophecy arc
- After the cats arrive to the lake, they wonder if StarClan will show them a place where they can communicate with them, such as the Moonstone in the old forest. Leafpaw is very restless, searching for any sign that can be interpreted as a signal to show a location of such a place.
- Spottedleaf visits Leafpaw in a dream, telling her that StarClan also had a difficult time finding a new meeting place, and that Leafpaw should follow starlit water to find it. Leafpaw takes Sorreltail, a fellow warrior, with her, and follows the stream that separate the ThunderClan and WindClan territories. They come upon a stone hollow with a starlit pool, and Leafpaw sees the reflection of StarClan warriors in the water. She discusses with several StarClan warriors then returns to the Clan to bring them the news.
- Leafpaw names the pool the "Moonpool", and later Cinderpelt gives her her medicine cat name, Leafpool, in honor of her discovery.
- It is revealed that Onewhisker made the journey to the Moonpool in order to receive his nine lives and new name from StarClan, making him the first leader to do so in the new territories.

In the Power of Three arc
- Jaypaw dreams of the path to the Moonpool, and when he follows Leafpool while she travels to the Moonpool, he recognizes the path and is able to visualize it in his head. When they reach the hollow, he follows her, and feels other cats brushing past him, though there seems to be no one else there. He realizes Leafpool is sleeping and he does the same, letting his nose touch the Moonpool.

On awakening, Leafpool is shocked and angry to find him there, and they leave the Moonpool after she questions him.

On reaching the hollow, the invisible voices welcome him again as he goes down to the pool and touches his nose to the water.

- All the medicine cats, except Flametail and Littlecloud, visit the Moonpool at the half-moon. Despite the cold weather, the Moonpool has not frozen over. All of the medicine cats experience the same dream; a StarClan ancestor from their own Clan tells them the Clans must stand alone, apart from each other.
