At Snowfield Stable, the reunited music troupe needs a roof for their wagon so they can reach the Great Fairy.
Quest Location
Before you can start this quest, you need to complete The Hornist's Dramatic Escape, Honey, Bee Mine, and Serenade to a Great Fairy.
If you have completed those quests, this quest can be started at Snowfield Stable, at -1632, 2587, 0234 in the Hebra Region.
Help the Troupe
As with Serenade to a Great Fairy, make sure that you have a horse that can pull the cart, and the towing harness.
Then go to the pile of construction materials near the troupe's wagon and get a square wooden board. Attach it to the top of the wagon such that its shadow is completely covering the inside of the wagon. Then carefully ride your selected horse to the front of the cart and attach the towing harness.
Then talk to Mastro and tell him that you will take them.
Take the Troupe to the Fairy
Mastro said to go around from the left, so start by going north from the stable. You should be able to see the sparkling pink cloud from the fountain, so go toward it.
Be careful not to go up too steep of a slope, and keep an eye out for monsters and keep as much distance from them as you can. There are Bokoblins riding horses on the right, and a Gleeok on the left. You can safely gallop without problems for your passengers (except startling them), so it might be best to gallop away from any enemies pursuing you.
When you get close enough to the fountain, there will be a cutscene.
Quest Reward
Mastro gives you 100 rupees as a reward. You can also talk to Great Fairy Mija from now on to upgrade your armor, and all the Great Fairies can upgrade your armor to a higher level now.
