Blaino protects himself with his gloves, so you have to wait until he punches before you can hit him.

Blaino always spins his glove before the powerful punch, so just move out of the way when he does this. Don't bother trying to hit Blaino before he punches. Just keep moving and wait for Blaino to punch, then hit him. You can charge up a Spin Attack and use the Roc's Feather to jump toward Blaino, then release the Spin Attack. It will hit Blaino even if he has his gloves up.

From the room where you got the Nightmare's Key, go back the way that you came until you reach a Vire room. Go south from there until you are in a room with flying bombs, arrows, and hearts. Push one of the lower blocks into the lava and jump across, then go east.

Hot Head jumps in and out of the lava. If the lava splashes on you, it hurts you for a lot of hearts. Try to stay in line with Hot Head so the splashes can't hit you. When possible, shoot Hot Head with the Magic Rod. Doing so will make Hot Head's flames go away temporarily, and Hot Head will fly around the room for a while before jumping back into the lava and catching fire again. Hot Head will pause right after you knock its flames off, so be sure to keep shooting with the Magic Rod to hit it multiple times before it starts moving. Keep hitting Hot Head with fire from the Magic Rod and it will eventually turn into a smaller monster that jumps in and out of the lava quickly. Keep hitting it with the Magic Rod until it dies.
A Piece of Heart will fall from the ceiling directly onto you.

Go north to get the final Siren's Instrument: the Thunder Drum. With this, you can go to the Wind Fish's Egg.
