Memory Fragment (Left Edge)

The Memory Fragment (Left Edge) is a treasure in. It is a puzzle piece for the puzzle in the Memory Fragment Series, specifically the left edge piece.

Collecting the treasure
The Memory Fragment is inside of the frozen lake in the southwestern side of sublevel 2 of the Subzero Sauna. To collect this treasure, you must first dissipate the cold air to reverse the freezing of the lake, then throw 2 Blue Pikmin at it. The nearby Arctic Cannon Larva should be defeated first.

The Pikmin won't be able to take it back until the iron fences have been lowered, which requires the button in the lake at the center of the sublevel to be pressed. Even after that is done, an Iceblown Dweevil will fall from the sky when the Pikmin pass shortly after the treasure's lake. Finally, the Pikmin will want to carry through the lake at the center of the room, meaning they run a risk of being caught by the Puckering Blinnows. Either defeat those first, or instead freeze the lake to the north and use Ice Pikmin to carry, to make the Pikmin carry through there.
