Key of S-Dly

The Key of S-Dly (also known as Sky Temple Key 3) is the third Sky Temple Key required for access to the Sky Temple in Metroid Prime 2: Echoes. In the Poisoned Bog in Dark Torvus Bog, Samus jump into the Dark Water and destroy the Flying Ing Cache in a dead-end. The Light Suit is necessary as it provides immunity to the water.
