Forget the pond right now, JUST RIGHT you enter the Pharaoh Dream, go south one screen, in the next screen, go right. There is no mistake, only mine earlier, SORRY
In the Pharaoh Dream, JUST AFTER you enter the Pharaoh Dream, go south one screen, there lasers on the way, you can pass by them but will take damage, but you must pass. On then next screen, look for a passage on the right. There are the Royal Gardens.
