The Legend of Zelda: Oracle of Seasons/Woods of Winter and Snake's Remains

Snake's Remains may be only the second dungeon, but it is far more treacherous than Gnarled Root Dungeon. Deadly traps and more powerful foes await. The dungeon has two parts to it, and it proves a step up from before. You'll find being in here isn't so safe.

Dangerous Rooms and Tougher Battles
As soon as you enter the first room, you'll see it's dark, and the door ahead is locked. If you light both torches in this room with Ember Seeds, the door will open.
