The Grooming Station is a domed, open-sided hut containing a pool of water and a rotating rock wheel. The roof is depicted as shingled with green tiles. In the game, Dragons: Rise of Berk however, there is no pool of water, and there appears to be hot coals or fires underneath the roof.
The Dragon Grooming Station is a building for dragons to care for themselves. They can bathe, exfoliate, and possibly dry off over hot coals.
After eating their fill, our winged friends can soak in the dragon wash or take a hot coal bath to scrub off dead scales. We keep the temperature at a steady 900 degrees!
