Poison Moth's Lair

The, also known as Level 3, is the third OoS: in. Deep within this dungeon lies the third Essence of Nature, the Bright Sun.

Entrance to the Lair
The entrance to Poison Moth's Lair is carved into a rock wall within the Spool Swamp, fittingly surrounded by carvings of a moth. To access the swamp, Link requires Ricky's aid. This requires that he obtain Ricky's Gloves by defeating Blaino in a boxing match, which is how Ricky lost his gloves to begin with. To reach the lower areas of the swamp, where the dungeon is found, Link must open the floodgates within the swamp using the Floodgate Key obtained from the Floodgate Keeper's house.

To reach the entrance to the dungeon, Link must climb the vines up to the opening in the rock face. However, since these NaN Vines grow only in summer, Link must first acquire the power of the Spirit of Summer for his Rod of Seasons. Therefore, Link must return to the Temple of Seasons in Subrosia. The nearby portal to Subrosia is surrounded by pitfalls, high cliffs, and deep waters, which Link will need the help of one of his animal companions to traverse (either Ricky, Dimitri, or Moosh, depending on which flute Link obtained earlier on).

Themes and Navigation
The third dungeon of features sickly green floors and pale blue walls. The dungeon is composed of two floors, with two side-scrolling basement areas that lead to isolated rooms of the dungeon. Gaping NaN Pits on the second floor of the dungeon allow Link to drop down back into the first floor.

Only two Small Keys are found throughout the whole dungeon (plus the Boss Key). As in all the other dungeon of the game, there is also a Treasure Chest containing a Gasha Seed. In a room with shifting floors lies the dungeon's main OoS:, Roc's Feather, guarded by a Blade Trap and Arm Mimics. The Roc's Feather allows Link to jump across gaps and reach new areas of the dungeon. The Roc's Feather also allows Link to jump onto NaN Trampolines found within the dungeon, rocketing him up through the holes in the ceiling to the second floor.

The mini boss of the dungeon is Omuai, a trio of squids in shallow water. The boss of the Poison Moth's Lair is Mothula, hence the name of the dungeon. If Link falls through the gaps in the floors while fighting Mothula, he will drop back into the first floor of the dungeon. He will have to jump on a OoS: to return and restart the battle. After defeating Mothula, Link receives the standard Heart Container and the Essence of Nature he was searching for.
