How to Complete the Rushroom Rush Quest
Pirou at the Gerudo Canyon Stable claims that he can’t live without rushrooms, but because they grow on cliffs, he’s unable to pick them himself. He’s offered to trade a diamond for 55 rushrooms.
Find 55 rushrooms
Rushrooms can be found all around Hyrule, growing on the sides of cliffs and mountains. As you explore the world, make sure to keep an eye out for this ingredient!
Deliver the Rushrooms to Pirou
After finding 55 rushrooms, return to Pirou to hand them over. As a reward for completing his task, you can retrieve a Diamond from a chest located behind the stable. You can either sell this Diamond for a high price or use it as an ingredient when crafting.
