Where is the outer palace garden in the Deku Palace?
After getting some magic beans and a bottle of spring water in the grotto of the inner palace garden, walk to the entrance of the palace. From the two guards at the gate, walk across the wooden bridge, then use Deku Link to hop to the left from one lily pad to the next. Once you reach the end, the outer palace garden, there should be a patch of soft soil near the Deku Palace wall. Use some magic beans and a bottle of spring water to make a leaf transport appear. Ride the leaf to the top of the wall, and get off to reach the 2nd level of the inner palace garden, where you can used Deku Link to fly from one flower to another.
