The Legend of Zelda: Link's Awakening DX playthrough Part 6
0Level 3,Key Cavern. Two sections of this map,both shaped like keys. Another Eye in the floor right at the entrance repels you from the chest. This dungeon introduces Bob-Ombs,yet another Mario enemy. Hit them and they'll fly off until they hit something or decide to explode. Some types will start a countdown and try to explode by you. There's also teleporting birds that shoot at you in this place. The miniboss of this dungeon are these 2 black monsters that crawl along the floor. Place bombs in their paths so they eat them and blow up,they take 3 each to kill. You get the Pegasus Boots for beating them! Now Link can dash,enabling long jumps,and he can also dash through those black crystal thing now. There's a bombable wall nearby,inside,use a running jump over the pit to reach the Nightmare Key. You can also dash your way to that Eye in the floor at the start of the dungeon for a key,you'll need several to reach the boss room. BOSS FIGHT: Slime Eye. He won't appear at all until you dash into a wall and knock him down. Otherwise it drops enemies endlessly. Once on ground,slashing it forces it to slowly split in half,then dash through the center when it's at it's limit io cut it into two halves. Then simply finish them off with your sword. The Sea Lily's Bell,the 3rd instrument,is your reward for winning.
