What order do you press the planets on the fountain on astro knights island?
Take the Princess’s secret message from the Maid’s room (castle first floor left) and go to the upper floor of the Mill. The girl will give you the Cosmic Symbols card. Go to the plaque on the fountain, which is now activated. Press the three symbols (moon, saturn, and the star) and then push in the sun. This will open the way into the secret chamber.
