STORY OF SEASONS: Pioneers of Olive Town

To acquire a mount, you have two options:

1) The first option is a standard farming sim staple in the form of a horse. You can find a Horse in the third area, along with the dilapidated stable to house it, but you cannot ride or use it without repairing the stable. To repair the stable, you'll need to provide 50 lumber, 40 solid lumber, and 30 supple lumber. Once you've repaired it, befriend the horse to name and ride it.

2) The second option is when your scooter is repaired. This is actually tied to the Town Request progress. After having satisfied the seventh request from Victor, Clemens will approach you the following day and tell you the requirements left. He will ask for a Fulgurite, Arthurite, and Olive Crystal, all items you can acquire from draining puddles in each respective farmland area. The odds are low to get this with the larger amount of clay, but it is more likely to happen as you'll be draining a lot of puddles to level the skill.

Either of these are mounts. The scooter will always be positioned outside your house, making it faster to get to than wherever you may put the stable. Either way, whenever you start to ride will unlock this trophy. Happy trails, as the mount will help getting around the farmland and town properly.
