You find the members of a music troupe stranded at Woodland Stable, hoping to perform for the Great Fairy.
Quest Location
You can start this quest at Woodland Stable, which is located at 1047, 1143, 0022, after you have started the quest Potential Princess Sightings at the Lucky Clover Gazette, near Rito Village in Hebra.
Get a Horse and Towing Harness
To do this quest, you will need a horse that can pull. Special horses will have — instead of stars for the "Pull" value, which means that you can't use them to pull the cart.
You will also need the Towing Harness, which you can get by exchanging Pony Points at the ledger book inside of any stable. Read the Pony Points page to find out how to earn Pony Points.
Help the Troupe
Now that you have a horse that can pull, and a towing harness (see above), you can help the troupe.
First, look nearby for wagon wheels in a pile near the broken wagon, then attach a wheel to each side of the axle that has no wheels. Be sure to move the wagon off of the rock that it is on top of.
Then take a horse out of the stable that you want to pull the cart, and customize the horse with the towing harness.
Now carefully ride the horse in front of the wagon and use Ultrahand to attach the towing harness to the wagon.
When everything is ready, talk to Mastro and tell him that you will take the troupe to the fairy. The troupe will get into the wagon.
Get on your horse and go at a moderate pace along the road that goes up the slope, and go left at the fork. You should be able to see the pink sparkly cloud above the Great Fairy Fountain. Go toward that. When you get close enough, there will be a cutscene.
Quest Reward
Penn's reward depends on how many stories you have investigated. See Potential Princess Sightings for details.
Great Fairy Tera will mark the locations of the other Fairy Fountains on your map.
You can also talk to Great Fairy Tera from now on to upgrade your armor.
