"This island is going to disappear... Our world is going to disappear... Our world... Our... world..."
Nightmares are the main bosses that appear throughout Link's Awakening. Over the course of the game they try to stop Link from waking up the Wind Fish. One reason they are trying to stop him is that they don't want their world to disappear, which is what would happen if Link did succeed in waking the Wind Fish.

"HO HO HO! I'm your bad guy this time!! HO HO HO!"
Genie is the boss of Bottle Grotto. Genie is invincible while in a bottle. It first pops out of a bottle and shoots fire, but after Link breaks its bottle with the Power Bracelet, it goes around the room shooting fireballs at him. It is vulnerable to Link's Sword during that time. The Nightmare will pop back into a bottle after a few seconds and start the process all over again.

"NEENER NEENER! YOU CAN'T FIND ME! NYAH NYAH!"
Slime Eyes is the boss of Key Cavern. Link has to find it by hitting the wall, causing Slime Eyes to fall from the ceiling. It can be defeated by hitting its eye over and over using a sword equipped with the Pegasus Boots. After hitting it a bunch of times it will divide into littler pieces.

"BAH! I'm not going to hold back! I'm going to make you wish you were never born!!"
Evil Eagle is the boss of Eagle's Tower. The Grim Creeper rides on his back. The interesting thing about the battle with him is the face that it is fought all in side perspective like Angler Fish. He can be defeated in many ways, but the Hookshot is one of the best.

"We were born of nightmares... To take over this world, we made the Wind Fish sleep endlessly! If the Wind Fish doesn't wake up, this island will never disappear! We would have been the masters of this place... But you had to come here and disrupt our plans! Heh heh! You can never defeat us!!! Let's rumble!"
This seems to be the head leader of the Nightmares. There are six forms that appear throughout the battle: Giant Gel, Agahnim's Shadow, Moldorm's Shadow, Shadow of Ganon, Lanmola, and DethI. After all these forms are defeated, Link can awaken the Wind Fish.
