Skin of the Phoenix

The Skin of the Phoenix is a treasure in  found in the Aquiferous Summit and The Mud Pit. It is actually an origami crane folded out of red paper.

Aquiferous Summit
There is a Skin of the Phoenix hanging from a cobweb on the western portion of sublevel 2 of the Aquiferous Summit. To collect this treasure, you must have Oatchi, who cannot pass through the iron fence, meaning that you'll have to take the alternate route. To go through it, the sizzling floor must be extinguished, or Oatchi must have the Scorch Guard. Then, climb on top of the rock structure with Oatchi and press the button to lower the iron fences. Lastly, throw 3 Pikmin at the treasure to bring it down.

The Mud Pit
There is a Skin of the Phoenix stuck in the mud east of the center of sublevel 2 of The Mud Pit, next to a Sweat-Soaked Blue Bird. It is guarded by three Muckerskates, which should be defeated before attempting to collect it, although it isn't necessary to do so. To collect this treasure, you must throw 3 Winged Pikmin at it.
