I had to kill two more enemies in the first dungeon to make the boss dropping a fairy.
To avoid it I have to redo the 4th dungeon at the point where I killed those two bats at the beginning. Not killing them avoids that I have to kill two more enemies to get a fairy in the 1st dungeon. This is also needed to get 5 rupees in the first dungeon.
