Scorching Sandpaper Minor

Scorching Sandpaper Minor is a small portion of the Scorching Sandpaper Desert in Paper Mario: The Origami King. It contains the Temple of Shrooms, which is where the yellow streamer leads to. Shroom City is located to the north of this area.

When all four Desert Towers across the Scorching Sandpaper Desert are activated, their lasers activate a Magic Circle for an Earth Vellumental in the center of Scorching Sandpaper Minor. Using the Earth Vellumental's ability, the Temple of Shrooms rises from the ground, also revealing that the yellow streamer leads into the temple.

This area has a single Collectible Treasure (found behind the Temple of Shrooms after it is unearthed), a single ? Block, two Toads, and no Not-Bottomless Holes.

History
Shortly after coming into the Scorching Sandpaper Desert, Mario and Olivia find the yellow streamer leading into the ground. After the party finds Professor Toad, defeats the Fire Vellumental and lights up all of the three toad monoliths, a Magic Circle appears, letting them unearth the Temple of Shrooms.

After the trio defeats Hole Punch, the sun reappears, and they look up to its glare before leaving the Scorching Sandpaper Minor.
