Eggerland Meikyuu no Fukkatsu/The 5th big key and the North god

Key Room
Once you complete room F-3, you will open a door to this room. When you step inside, you will see four doors, one along each wall. Each door is locked with a large key, so you will need four large keys to open every room. Inside the treasure chest of each room is one of four corners to a tablet. In order to proceed to King Egger's maze, you must collect all four pieces of the tablet. Once you have done this, a door to the first room of the final maze will appear.

Top Room
Start by collecting the Heart Frame in the lower left corner, and luring the Leeper out. Stand near the trees on the right and let it touch you and fall asleep. Step back into the alley on the left and collect another Heart Frame, luring another Leeper out. Put this one to sleep close to the first one. Then step back in the left alley to collect the last Heart Frame. You should now have four egg shots. At this time, make your way to the top of the room and prepare to sweep through the right alley. Since you have four egg shots, its recommended that you shoot both of the remaining Leepers twice to remove them from the screen, and make it easier to clear the room faster.
 * Solution:

Right Room
Working your way around the room in a clockwise direction, collect each of the Heart Frames that sit directly in front of each Gol, saving the Heart Frame closest to the entrance for last. Collecting this last Heart Frame will give you two egg shots, which you will need to survive your escape from this room. When you're ready, stand half of a space between the two boulders to your left and approach the first Gol against the bottom wall. When you are lined up with him, face down, shoot one egg shot to block the fireball, and run to the right. The Gol on the right wall will shoot a fireball at you, but you can easily dodge it, and get past the trees to start heading up before the first fireball reaches the end. Next, you will approach the Gol along the top wall the same way that you did with the Gol on the bottom wall, shooting one egg shot at the Gol as you line up with him, before quickly ducking into the path on the left. Watch out for the left Gol's fireball and collect the tablet corner.
 * Solution:

Bottom Room

 * Solution:
 * 1) Collect both Heart Frames near the top of the room for two egg shots.  Then approach the pair of Heart Frames blocking the left Alma in.  Collect them when the left Alma is moving down, and then stand up by the bridges when the Alma chases you.  Turn around and shoot the Alma, and push the egg straight up to the left side of the left Emerald Frame.  Hop on the egg, and when you are above the Emerald Frame, push it down one space.
 * 2) While you are waiting for the Alma to respawn, push the Emerald Frame to the left half of a space, and then down one more space.  The Alma will reappear and head up to the Emerald Frame.  After touching it, it should move down into the left alley with the two Medusas.  At this time, push the Emerald Frame down to trap the Alma in the alley.  Then push the frame over to the left, and push it down until it half blocks the lower portion of the higher Medusa.  The Alma will serve to block the lower Medusa's sight.
 * 3) Repeat the same exact process on the right side with the right Alma.  When you have the Emerald Frames and Almas in place, you may collect the remaining Heart Frames along the bottom wall, and collect the next tablet corner.

Left Room

 * Solution:
 * 1) Start by moving the Emerald Frame near the entrance down two spaces, and over to the left two and a half spaces.  Once again, you must run along side the Don Medusas in order to survive being seen by the Medusa in the center.  Do this along the outer edge of the room, leaving all of the remaining Emerald Frames in there place for the time being.  Collect the Heart Frame in the upper right corner of the room.
 * 2) Come back to the highest Emerald Frame and, when it's safe, push it to the left one and a half spaces.  Then, when the highest Don Medusa is to the right side, push the Emerald Frame down, trapping him in, but not pinning him.  Then watch the movement of the other two Don Medusas, and collect the Heart Frame above the Medusa.
 * 3) Come down along the left side, pushing the left Emerald Frame down one and a half spaces as well, and then left one space to trap the Don Medusa in above you.  Carefully dash in to collect the Heart Frame to the left of the Medusa.
 * 4) Finally, come down along the bottom, push the low Emerald Frame on the left one and a half spaces to the right, and then up to trap the lower Don Medusa in on the left.  Collect the last Heart Frame, and the tablet corner.
