The reflecting pool is a location in the Smurf Forest.

In the cartoon episode "Love Those Smurfs," it is a pool hidden deeply within a cave somewhere in the forest, as seen visited by Vanity, Brainy, and Snappy. As Brainy explains, the minerals (mostly represented as gemstones) that make up the walls of the cave are what gives the pool of water its reflective nature. It is maintained in this seemingly unchanging state because the wind never flows through the cave, meaning there is no erosion or rippling to cause decay.
