Being able to take your horse around everywhere in The Legend of Zelda: Tears of the Kingdom makes completing tasks much easier. Especially when you are needing to tow around items, including Koroks looking to reunite with their friends.
In Horse-Drawn Dreams, Zumi wishes she could have the luxury of catching a wild horse and using it for her towing needs. However, she is having trouble getting one and fixing up her wagon, which is where Link will come in to save the day.
Where To Find Horse-Drawn Dreams
You can find the Horse-Drawn Dreams side quest at New Serenne Stable within the North Hyrule Plain region west of Hyrule Castle. As soon as you arrive at the stable, all you will need to do is talk to Zumi just outside, standing next to the broken-down wagon to the left. She will mention that she wants to fix up her wagon and catch a wild horse to tow the wagon, but she isn't sure how to go about completing these tasks. This is when the quest will begin, and you'll start the journey towards fulfilling Zumi's dreams.
How To Complete Horse-Drawn Dreams
The first thing we will do for Zumi is find a couple wheels to attach to her broken wagon. Start by heading down the path on the left, following north up the road towards the Royal Ancient Lab Ruins. Eventually, you'll come across a spot on the right with a bunch of building materials you can bring to Zumi. If you already have a towing wagon, you can place the two wheels inside the wagon and use your horse to tow the materials back to the stable. If you don't have a wagon, you can create your own with the materials given.
We attached three wooden boards together to make a wagon and then two long planks on the ends to attach the four wheels to. You can use the above image as reference on how to build the wagon. Then, attach your hand-made wagon to your horse's towing harness and return to the stable.
When you arrive, take the two wheels out of your wagon and attach them to the missing spots on Zumi's wagon. She will then thank you for fixing it up, and all you will need to do now is find a horse for her to use.
Luckily, there are quite a few horses nearby to the east. They'll be on the geoglyph on the field next to the stable, shown on the map above. Pick whichever horse you prefer, and make sure to sneak up on it from behind by crouching. Then, jump on top and soothe the horse as much as possible to get it to cooperate.
Finally, return to the stable with your new horse and approach Zumi. Stay on top of the horse, and use ZR to target Zumi and press A to talk to her. You'll then be able to hand over the horse to her, completing the quest. Zumi will provide you with a Silver Rupee, equivalent to 100 Rupees.
