Eggerland/Row 9

Left Room
Solution: ''When you complete the room, leave and return. Push the lower Emerald Frame on the center island to make a Guardian Chamber entrance appear.''
 * 1) Save the Heart Frame directly south of the treasure chest for last.  Walk past it and up to the Emerald Frame near the chest.  Push it left all the way to the Heart Frame against the wall, collecting the Heart Frame between the two Skulls along the way.  It will give you two Egg shots.
 * 2) Shoot the upper left Skull twice to remove it and push the Emerald Frame down until it is in front of the Medusa.  Then collect the two nearby Heart Frames, and cross the bridge to the right and collect the next Heart Frame.  Push the two Emerald Frames up and down, stopping just before the Skulls.
 * 3) Walk back to the center, to the left, and up and around, pushing the Emerald Frame close to the treasure chest.  Stop when the frame is over the bridge, then walk around to the right side and push the frame back to the left, all the way again.
 * 4) Double shoot the Skull again and push it down to the Emerald Frame below.  Then walk back up, to the right, and down to the center and to the left, to push the frame above the Medusa.  Then walk up the bridge above to collect the Heart Frame.
 * 5) Walk back to the lower right corner, and walk to the left across the bridges, pushing the Emerald Frame that you pushed down to the left.  Collect the Heart Frame between the Skulls along the way.  Double Shoot the lower Skull and push the Emerald Frame up to the frame above.  Then walk back down, right, up to the center and to the left.  Push the lower frame below the Medusa.
 * 6) Walk down the bridge and collect the lower left Heart Frame.  Then walk to the Heart Frame that you saved for last, and quickly run up to the key before the Skulls get too close to it.

Guardian Chamber
There are only 14 seconds on the clock, and you have to find the right path to reach the chest before time runs out. Despite appearances, there's only one entrance to the chest.
 * 1) From the start, run straight right to the upper right corner.
 * 2) Then run straight down to the lower right corner.
 * 3) Run straight to the left until you are under the second up Arrow Tile, then walk up and collect the chest just in time.
