Key of J-Fme

The Key of J-Fme (also known as Sky Temple Key 9) is the ninth and final Sky Temple Key required for access to the Sky Temple in Metroid Prime 2: Echoes (the Key of A-Kul was already placed at the Sky Temple Gateway). In the Accursed Lake in the Sky Temple Grounds, Samus must locate the Flying Ing Cache in the air in another spectrum, then destroy it to obtain the Key. It can be obtained before the Light Suit, though it would come in handy were Samus to fall into the Dark Water.
